Some insights for Democrats in “Black Voters Are Transforming the Suburbs — And American Politics: An influx of Black voters into suburbia holds enormous promise for Democrats, but Republicans are fighting back” by David Siders, Sean McMinn, Brampton Booker and Jesus A. Rodriguez at Politico:

Around the country, the number of Black people living in U.S. suburbs ballooned during the first two decades of this century, increasing from 8.8 million to 13.6 million nationwide, according to POLITICO Magazine’s analysis. Today, more than one-third of Black Americans live in suburban areas — the fastest-growing areas in the country for Black people.

At first blush, the suburbanization of the Black vote holds enormous promise for Democrats, pushing the party’s most loyal base of voters into suburban areas that, in recent election cycles, have determined the balance of power in Congress and the presidency. According to a POLITICO Magazine analysis of election results from last month’s midterms, Democrats dominated suburban districts that saw a large influx of Black residents over the last two decades. Even in red states like Texas, where the Black population is eclipsed by white and Latino voters, Black people are by far Democrats’ most dependable constituency, with 84 percent of Black voters in Texas last month casting Democratic ballots in the state’s gubernatorial race, compared to 57 percent of Latinos and 33 percent of whites, according to exit polls.

“When you think about the suburbs becoming more diverse,” said Tom Bonier, CEO of the Democratic data firm TargetSmart, “it just creates a way more efficient distribution of Democratic votes, where they’re not as packed into the cities.”

The most recent example: the once reliably red state of Georgia, which has shifted in favor Democrats in the last two election cycles. The historic Senate runoff this month featured for the first time in modern Georgia — and one of the handful of instances in American politics — two Black nominees: incumbent Democrat Raphael Warnock, the state’s first Black senator and an activist pastor who leads Martin Luther King Jr.’s church in Atlanta, and Republican Herschel Walker, a former running back and Heisman Trophy winner who had the backing of former president Donald Trump. Warnock’s victory, by roughly 97,000 votes, was secured by maintaining Democratic gains in counties that had traditionally voted Republican, including the Atlanta suburbs of Cobb and Henry counties.

The authors also note that “The migration of Black populations away from city centers to the nation’s suburbs is happening across the U.S., from southern cities like Houston and New Orleans to midwestern cities like Chicago to western cities like Oakland and Los Angeles, and all down the East Coast, from New York to Washington to Atlanta.” Further,

For Democrats laboring to take advantage of the rapidly diversifying suburbs, a bigger challenge isn’t the Black candidates Republicans are running, but total Republican control over redistricting in states like Texas. The constitutionally authorized process, by which state legislatures take census data and redraw their congressional maps, often means whichever party controls a state legislature gets to shape districts to its benefit — as long as there is no overwhelming evidence of racial discrimination.

According to the progressive Brennan Center for Justice, Republicans controlled the drawing of 177 House districts in 19 states, or 41 percent of the lower chamber’s seats, in redistricting’s last round. Democrats, by comparison, control redistricting in seven states, or 11 percent of seats. (Other states use less partisan venues to draw maps, such as independent commissions or courts, which represent 40 percent of House seats.) In the past, Republicans have used the process to draw maps that dilute the voting power of urban areas, which tend to elect Democrats, by carving them up and joining them with more conservative suburbs. But voting rights experts say that Republicans are increasingly targeting the suburbs themselves, which are becoming more liberal as Black voters and other voters of color move there. Their strategy: merging those diversifying suburban districts with rural areas, which tend to vote red.

The diversification of America’s ‘burbs’ is a pivotal trend, juiced by accelerating in-migration in many southern and western states. Much depends on how well the Democrats craft their messaging in these areas in 2024.
