I made this simple map to show the population shifts from 2020 to 2025 in #Pennsylvania. I grouped counties together based on whether they were gaining or losing population.
Basically, eastern PA (besides Philly) has been growing steadily. South Central PA especially stands out.

👀 AUDIO: At a recent tele-town hall, GOP Rep. Scott Perry of Pennsylvania doesn’t forcefully condemn constituent who said Hitler ‘should have finished the job’ of killing all Jews during WWII.
Perry (toward the end): “I just don’t think any of that is helpful at all. You know, we respect everybody’s religion…” ⬇️
The Pennsylvania Republican previously faced backlash over an posting an antisemitic meme, his defense of the “Great Replacement” theory, and for vote against a bipartisan House resolution condemning the QAnon movement.

Janelle Stelson raised $2.1 in the first quarter of 2026 in her race against Scott Perry. For context, Stacy Garrity raided a little over $1 million for her #pagov campaign.

I made some maps of the 2025 election results in @ChrisForPA’s district (PA-17), and Dems truly swept across the board:

Last night, Democrats in Pennsylvania flipped:
Bucks County District Attorney (for the first time ever!)
Bucks County Sheriff
Erie County Executive
4 Luzerne County Council seats (to regain control of the Council)
Mayor of Beaver Borough
Judicial seats across the Commonwealth
…. and more.
That’s on TOP of retaining the Supreme Court justices.
It was a good night, folks. Let’s have another one on November 3, 2026.

Behold - the 2020-2024 United States Presidential Election Results, Swings, + Trends in Allegheny County, Pennsylvania + DLC.
Allegheny County largely avoided the ugly rightward shift that many other large counties in the state and country fell victim to. 🧵

“Rep. Rob Bresnahan, a multimillionaire who recently sold control of his family’s company and now represents one of Pennsylvania’s poorest congressional districts, appears to have taken steps to hide one whirling aspect of his wealth: his new personal helicopter.” #PA08

I do want people to grapple with this: if "whites are very racist" was the driver behind Kamala Harris running behind Biden, as I've seen bandied about in liberal (and donor!) circles, then the white rurals in PA should not have been the places she did best in, relative to 2020.

It's out! 80 years ago, in 1945, when WW II ended, East Prussia was wiped out. Historically the area was German but with sizable Lithuanian, Polish, and Masurian minorities.
I have digitized the *entire* East Prussian census of 1905.

With Election Night Results finished Democrat James Malone appears to have Flipped Pennsylvania's 36th Senate District after Trump won it by ~15% in 2024 the district covers around half of Lancaster County.

I have seen Democrats say they need to pick white men to win again.
This is incredibly stupid, because the data shows that voters do not care about identity politics in the way that Democratic elites think they do.

#ElectionTwitter Here's a dot map of the shift in raw votes by county in Pennsylvania from 1956-1960. Kennedy netted hundreds of thousands of new votes in Philadelphia, Pittsburgh, and Scranton-Wilkes Barre, which far outweighed the gains that Nixon made in Central Pennsylvania.

The Northeast Corridor has long been the most urbanized area in the country. Though the region has remained firmly Democratic for decades, the GOP has made major inroads here in the Trump era. Here is a map of Harris' performance last year. A🧵

I think it's worth noting that excluding the cities of Harrisburg, York, and Lancaster, Dutch Pennsylvania as a whole shifted leftward last year

A big lesson of 2024 was that extremism loses votes — and the sooner we stop pretending that Americans are secret lefties/MAGA diehards waiting to be sold on a big, bold message, the better we’ll understand what happened.

Today, I wanted to revisit my Bob Casey thread from November with all the recent talk of Fetterman’s “MAGA transformation” (aka moderation). Casey ran into a lot of the same issues Sherrod Brown ran into in OH (see yesterday’s thread): rural/WWC loss. 🧵🗺️🗺️

🧵 Trump & Congressional Republicans are planning billions of dollars of cuts to SNAP food stamps. Political & economic problems may arise in congressional districts that rely the most on food aid, so let’s examine who they are (tag your local journalists):
