Blue Wave Rising in PA

Timothy P. Carney reports on “Pennsylvania’s Blue Wave” at aei.org and writes:

MECHANICSBURG, Pennsylvania — Pennsylvania is arguably the swingiest of swing states.

The Keystone State has voted for the winner in each of the last five presidential elections, and it has been a tipping point in each of the past three elections.

It is one of only four states with one Democrat and one Republican in the Senate. In the state government, Republicans and Democrats have split power for the past decade. The state House of Representatives is divided 102 to 101.

But this will not last.

A blue wave is likely to hit Pennsylvania this year, easily carrying Gov. Josh Shapiro (D-PA) to reelection, and very possibly handing the state Senate, and thus a governing trifecta, to Democrats. In fact, the blue wave already began two months ago as Democrats dominated in local elections and statewide judicial races in 2025.

It’s true that President Donald Trump has revived Republican fortunes in this state. Not only did he win twice, but he also had large coattails, helping Republicans win the Senate races in 2016 and 2024.

But Trump will never be on a ballot here again, and that ought to make Republicans even more worried about today’s political currents. This may not be a mere tidal wave. Tidal waves eventually recede. The 2025-2026 Pennsylvania blue wave looks to instead be a sea change, in which the Keystone State becomes solidly Democratic for a decade or more.

Pennsylvania After Trump

The key dynamic in Pennsylvania politics is the political realignment in which the working class is becoming solidly Republican, while upper-middle-class suburbanites are becoming more Democratic.

This realignment isn’t limited to Pennsylvania, and it didn’t start with Trump. Still, Trump put the realignment into overdrive, and Pennsylvania is where it’s most visible.

When Trump ran in 2016, no Republican had won the state since 1988, and former President Barack Obama had won it pretty easily. Then Trump came by and made massive gains in the coal country of central Pennsylvania and in steel country around Pittsburgh.

You can explain Trump’s 2016 outperformance of 2012 Republican presidential nominee Mitt Romney just by counting four adjacent counties running from former steel country south of Pittsburgh, Fayette County, to Blair County in central Pennsylvania, with Cambria and Somerset in the middle. These counties have far lower incomes and educational attainment than the rest of the state, and they handed Trump his victory: Trump’s excess margin of victory across the four counties, compared to Romney, more than covers Trump’s statewide margin of 44,292 votes in that election. This is Trump country.

Look at Philadelphia’s collar counties, and you see the opposite trend: The upper-middle-class suburbs, especially Chester and Montgomery counties, tacked hard toward the Democrats.
