All of us in the chattering classes had an immediate reaction to the release of the redacted Mueller Report. Here was mine at New York.

Mueller lets us know (directly contradicting Barr’s repeated assurances that it was lack of evidence, not the legal standard, that prevented criminal accusations) that he decided not to pursue a “traditional prosecutorial judgment” on possible obstruction of justice in order to comply with the DOJ’s position against prosecution of sitting presidents:

“The Office of Legal Counsel (OLC) has issued an opinion finding that ‘the indictment or criminal prosecution of a sitting President would impermissibly undermine the capacity of the executive branch to perform its constitutionally assigned functions’ in violation of ‘the constitutional separation of powers.’ Given the role of the Special Counsel as an attorney in the Department of Justice and the framework of the Special Counsel regulations, see 28 U.S.C. § 515; 28 C.F.R. § 600.7 (a), this Office accepted OLC’s legal conclusion for the purpose of exercising prosecutorial jurisdiction.

In a sort of Catch-22, Mueller then concluded that it wouldn’t be fair to Trump to accuse him of criminal conduct if he wasn’t going to be hauled into court and given an opportunity to properly defend himself.

“Fairness concerns counseled against potentially reaching that judgment when no charges can be brought. The ordinary means for an individual to respond to an accusation is through a speedy and public trial, with all the procedural protections that surround a criminal case. An individual who believes he was wrongly accused can use that process to seek to clear his name. In contrast, a prosecutor’s judgment that crimes were committed, but that no charges will be brought, affords no such adversarial opportunity for public name-clearing before an impartial adjudicator.”

And then there’s this tantalizing passage:

The footnote to the italicized portion reads: “See U.S. CONST. Art. I § 2, cl. 5; § 3, cl. 6; cf OLC Op. at 257-258 (discussing relationship between impeachment and criminal prosecution of a sitting President).”

So very carefully Mueller is suggesting: Here’s what the president did. I can’t do anything about it, so I will not call it criminal. Use my findings to impeach him if you wish, Congress.

As Nancy Pelosi could tell you, there are solid practical grounds for the U.S. House of Representatives to eschew impeachment proceedings, beginning with the fact that there is approximately zero chance the Republican-controlled Senate would vote to convict Trump, particularly now that we are in the active phase of a presidential election cycle. So it may well be that the best Democrats, and Trump’s other critics, can do is to take Mueller’s findings and whatever else other prosecutors or House investigators can uncover, and present it clearly as part of the case against the man’s reelection.

Watching as the MSM had great sport with snippy-grams going back and forth between House Democratic leaders and their new super-star freshman Alexandria Ocasio-Cortez, I tried to think through the deeper implications at New York:

Nancy Pelosi’s comments at the London School of Economics explaining the fruits of partisan gerrymandering made their way back across the pond with lightning speed, as reflected in the Washington Examiner:

“Pelosi explained to the London school audience that her district as well as the one represented by [Alexandria] Ocasio-Cortez vote Democrat no matter what.

“’This glass of water would win with a “D” next to it in those districts,’ Pelosi said. ‘But that’s not where we have to win elections.’”

Just to be clear, Pelosi’s right about the noncompetitive nature of her own San Francisco House district and AOC’s in New York: The former is the sixth-most Democratic district according to the Cook Political Report’s Partisan Voting Index (PVI), and the latter is the 31st-most Democratic. Hillary Clinton won 77 percent of the vote in AOC’s district, and Obama won 81 percent in 2012.

Presumably Pelosi thinks that despite her own safe seat, she can understand the plight of Democrats representing swing districts, but apparently has doubts about aggressively progressive members like AOC:

“’This is about winning,’ Pelosi told the London School of Economics and Political Science. ‘When we have to go into the districts we have to win, we have to cull that to what we have in common with those people.'”

Now Pelosi also had words of praise for her preternaturally talented young colleague. But you have to figure she wishes AOC, who has replaced Pelosi as the principal target of sexist conservative agitprop, had a slightly lower profile.

It’s unclear how any of this threatens Pelosi’s majority, except insofar as conservatives have sought to identify the entire Democratic Party with this one democratic socialist member’s views — which of course they are going to do in any event. Unless the entire House Democratic Caucus is expected to repeat the party line like cicadas, then there will always be members from districts where a more progressive viewpoint is viable than is politically sustainable everywhere. Their job is precisely to keep pressure on the leadership and the party to represent their constituents, too — not just the swing voters who have very nearly been hunted to extinction. And it doesn’t mean Democrats cannot accommodate candidates and members in more competitive districts with views more appropriate to local conditions. The big-tent principle should, however, work both ways.

If AOC begins threatening primary challenges to loyal Democrats from swing districts who happen to disagree with her ideology or policies, or suggesting Democrats take a dive in national elections if their candidates are too “centrist,” then that’s a clear violation of party discipline and Pelosi would be justified in rebuking her. That hasn’t happened, though. So long as gerrymandering and simple concentration of partisan voters produces safe House seats, however, their valuable function is to produce restless insurgents who stretch the imaginations of their elders rather than time-serving perpetual incumbents who go along to get along. In truth, both Pelosi, the precedent-shattering Speaker, and Ocasio-Cortez, the progressive comet, represent the silver lining of the generally rotten system of partisan gerrymandering: It gives leaders the opportunity to emerge from the crowd of election-fearing pols.

Democrats should get ready for the intensive campaign of demonization Republicans are planning for them. I wrote about this again at New York this week.

Perhaps he was just stating the obvious, but it did have the ring of an official announcement when Senate Majority Leader Mitch McConnell suggested a GOP-wide message for 2020, as the Hill reports:

“We need to have a referendum on socialism,’ McConnell told a group of reporters when asked for his assessment of next year’s elections, when Senate Republicans will have to defend 22 seats, compared with 12 for Democrats.”

In case reporters somehow didn’t get it, McConnell restated the proposition:

“’I’m going to be arguing, and I’m encouraging my colleagues to argue, that we are the firewall against socialism in this country,’ McConnell added …

“’We’ve got five credible candidates for president in the Senate signed up for the Green New Deal and Medicare for none. If we can’t make that case, we ought to go into another line of work,’ he said.

“McConnell argues that will be the key to reversing the drop in support among women and college graduates that hurt Republicans in the 2018 midterm elections, when Democrats won back the House and captured GOP-held Senate seats in Arizona and Nevada.”

So there you have it: Red Scare 2020 is going to be a big and abiding thing. This clearly syncs Senate Republicans with the Trump reelection bid. It’s long been clear that his 2020 strategy will be what you’d expect from an abidingly unpopular president leading an unpopular party with unpopular policy positions: a relentlessly negative attack on his Democratic opponent using every weapon available. There’s some irony involved in a Trump-led party accusing its opponents of “extremism,” but it’s an age-old tactic: When you cannot credibly occupy the “political center,” you can always try to push your opponents even further from the center than you are.

And “socialism” is a time-tested epithet for left-of-center politicians and parties. With older voters, of course, it connotes not just big government but the “scientific socialism” of Marxism-Leninism, along with the Soviet imperialism that formed so large a part of the experience of Americans in and before the baby boom. But it’s a big target generally, as David Graham has explained:

“Though it feels like a Cold War throwback, the socialism epithet might be effective. It could resonate with a wider swath of the public than some of Trump’s other signature lines. The border wall, for example, is unpopular with Americans overall, though very popular with the president’s core supporters. By contrast, voter antipathy toward socialism is much broader: In a February Fox News poll, 59 percent of Americans held an unfavorable view. As of 2015, half of Americans said they wouldn’t vote for a socialist (though only 38 percent of Democrats held that view).”

The “socialism” label for Democratic policy proposals could also help expose divisions in the Donkey Party’s ranks over significant variations in how to define the Green New Deal and how to implement Medicare for All, as candidates not named Bernie Sanders (the only self-identified “socialist” in the presidential field, so far at least) try to distinguish their approaches from his.

On the other hand, conservatives have been calling liberals “socialists” for eons, and it’s no automatic magic bullet. Most notoriously, Barack Obama was relentlessly (if ridiculously) called a “socialist” by Republican-aligned media types going into the 2012 election, and it didn’t appear to work. For that matter, Trump himself deployed the “socialist” epithet toward Democrats going into the 2018 midterms, to no discernible effect.

But when you can’t say much about your own party’s record other than pointing at economic indicators and hooting “Mine! Mine!” then creating and burnishing negative associations for the other side may be the only available strategy.

One of the most tiresomely mendacious memes out there arose this week in congressional testimony, so I tried to blow it up one more time at New York.

There is a revisionist historical theory you hear now and then among conservatives — particularly African-American conservatives who are understandably a mite defensive about their position as a minority of a minority — holding that everything we think we know about the partisan politics of the post–civil-rights era is untrue. And it was enunciated again by the recently famous African-American pro-Trump activist Candace Owens, who was brought in by House Republicans to mock and disrupt a hearing Democrats convened on white nationalism, as the Washington Post reports:

“Owens, who tried to diminish the rise of white nationalism as an invention by Democrats to ‘scare black people,’ said there had never been a Republican effort to use racism to the party’s political advantage.

“‘Black conservatives are criticized for having ‘the audacity to think for themselves and become educated about our history and the myth of things like the Southern switch, the Southern strategy, which never happened,’ she told lawmakers.

I do not know if Owens subscribes to the fully developed right-wing theorythat white racist Lyndon Johnson concocted the Civil Rights and Voting Rights Acts and the Great Society program as part of a white racist conspiracy to ensnare African-Americans in the “plantation” of dependency on government. But I wouldn’t be surprised. It’s hard otherwise to deny the basic facts that southern white racists steadily moved, from the early 1960s to the 1980s, from their old stronghold in the Democratic Party to their new home in the GOP — the “southern switch” — or that Republican pols in and beyond the South pursued this development as a “strategy.”

And of course Republican pols, racist or not, promoted this development as a strategic masterstroke. In a 1970 interview with the New York Times, Kevin Phillips, the prophet of The Emerging Republican Majority and wonder-boy Nixon strategist, put it this way:

“From now on, the Republicans are never going to get more than 10 to 20 per cent of the Negro vote and they don’t need any more than that … but Republicans would be shortsighted if they weakened enforcement of the Voting Rights Act. The more Negroes who register as Democrats in the South, the sooner the Negrophobe whites will quit the Democrats and become Republicans. That’s where the votes are.”

Nixon himself was famously in thrall to old-school southern segregationists like Strom Thurmond, who was given a veto over the 1968 vice-presidential nomination and over the administration’s Supreme Court appointments. His landslide reelection in 1972 was in no small part attributable to the capture of the entire 1968 George Wallace vote. Ronald Reagan beat Jimmy Carter in 1980 in part by convincing conservative white southerners finally to abandon Democrats once and for all. And the southern strategy was avidly pursued by later GOP strategists from Lee Atwater to Karl Rove.

Now a lot of people don’t know much about political history, and followers of a president who doesn’t read and routinely disregards facts probably can’t be expected to document their own myths very carefully. But they need to be challenged regularly.

An old debate among Democrats has been revived, and I wrote about it at New York:

Political writers have understandably tried to make sense of the large 2020 Democratic field of presidential candidates by sorting them out ideologically (“left” or “center”) or by indicators of policy audacity (“bold” progressives versus “cautious” or “incremantalist” moderates). And part of the reason for the general belief that the party is “moving to the left” is the clustering of presidential candidates around policy positions (e.g., single-payer health care or a Green New Deal) that were considered “radical” not that long ago.

But as Ezra Klein observes after interviewing Pete Buttigieg, the most important differences may have less to do with what the candidates want to do and more with how they plan to do it — their theory of change:

“The central lesson of Obama’s presidency, Buttigieg argues, is that ‘any decisions that are based on an assumption of good faith by Republicans in the Senate will be defeated.’ The hope that you can pass laws through bipartisan compromise is dead. And that means governance is consistently, reliably failing to solve people’s problems, which is in turn radicalizing them against government itself.”

Which is, of course, precisely the way obstructionist Republicans led by Mitch McConnell planned it.

“Buttigieg’s response — one that you also hear from 2020 hopefuls Sen. Elizabeth Warren and Gov. Jay Inslee — is to restructure government so popular majorities translate more cleanly into governing majorities. He’s discussed eliminating the Electoral College, scrapping the filibuster, and remaking the Supreme Court so each party nominates the same number of justices and vacancies become less ‘apocalyptic.'”

There is not, however, any easy equivalence between the audacity of policy proposals and the willingness of candidates to consider the “process” changes that could make achieving these policies possible, as shown by Bernie Sanders, the “radical” who wants to preserve the filibuster and the current system for selecting Supreme Court justices. And indeed, you could imagine that a newly elected president who’s on fire to enact Medicare for All might not be initially inclined to spend political capital on boring process issues. As Klein says: “It’s easier to run for reelection bragging about a tax cut than about weakening the Electoral College.”

Klein points to a very useful 2007 essay by Mark Schmitt urging Democrats with very similar policy goals to focus on ways and means of achieving them:

“[Schmitt] argued that the contest between Barack Obama, Hillary Clinton, and John Edwards was ‘not a primary about ideological differences, or electability, but rather one about a difference in candidates’ implicit assumptions about the current circumstance and how the levers of power can be used to get the country back on track.’ It was, he said, the ‘theory of change primary.'”

You can look back and say (as I just did) that Obama’s “theory of change” turned out to be significantly wrong. But in the circumstances of 2009, it’s unlikely that either Hillary Clinton’s claim of hard work being the answer, or John Edwards’s appeal to pure confrontation, would have done much better. So now, given the enduring reality of Republican obstruction, and their reliance on institutional barriers to democracy and change, having a clear-eyed understanding of the prerequisites to policy achievements is an absolute must for the 46th president. And this should not be a topic confined to elites; Schmitt’s proposed “theory of change primary” can and should be held in the early televised debates and on the campaign trail.

To put it another way, Donald Trump should be the last U.S. president to take office with no clue about how to implement his campaign promises.
