President Donald Trump may not be the kind of Republican traditionally associated with Pennsylvania, but voter registration numbers suggest the GOP is gaining ground under his leadership — including in the Delaware Valley.

According to the Pennsylvania Secretary of State’s Office, there are currently 3,580,027 active Democratic voter registrations statewide, compared to 3,512,392 active Republican voters — a gap of fewer than 70,000 voters.

That number sent GOP voter recruitment guru Scott Presler to social media to shout the news. “This is the lowest Democrat voter registration advantage in modern history!” he posted on social media.

Presler, the Pied Piper of GOP voter registration, is founder of Early Vote Action, a group focused on GOP voter registration via social media.

When Donald Trump first ran for president in 2016, Democrats had a massive 4.1 million to 3.2 million registered voter advantage — and Trump still won the state over Hillary Clinton.

“I think it’s very energizing for Republicans,” said Vince Galko, former executive director of the Pennsylvania Republican Party. “It’s got to be a doomsday scenario for Democrats. They’re hemorrhaging voters and they don’t have a way to stop it.”

And Presler says the news for Democrats isn’t going to get any better.

“We contact every single person we register to vote in order to mobilize them to vote,” Presler said. “We don’t just register voters — we follow up with them.”

The shifting voter landscape is particularly evident in the Delaware Valley.

After decades as a Republican redoubt, the region flipped blue in 2019 when Democrats took control of the county councils in Bucks, Chester, Delaware, and Montgomery counties. But Republicans believe momentum may be shifting their way once again.

In Bucks County, registered Republicans now outnumber Democrats by nearly 12,000 voters. That shift has coincided with rising support for U.S. Rep. Brian Fitzpatrick (R-Bucks), whose vote total increased from 207,263 in 2016 to 261,390 in 2024.

And while Democrats still control the county council, Republicans now hold more row offices — five compared to the Democrats’ four.

Chester County is also showing signs of change. Two years ago, Democrats held a voter registration edge of more than 8,000. Today, that gap has shrunk to under 6,000 — and to less than 3,000 among active voters.

Still, Republicans face steeper challenges in Delaware and Montgomery counties.

In Delaware County, Democrats currently lead Republicans by about 55,000 registered voters — down from more than 57,000 in 2023. Among active voters, the Democratic advantage stands at nearly 48,000. Democrats hold every elected office in the county, but Republicans hope to flip several row offices this year, particularly the sheriff’s seat, as incumbent Jerry Sanders Jr. is not seeking reelection.

Montgomery County remains the GOP’s biggest hurdle. Democrats outnumber Republicans by nearly 90,000 voters — both registered and active. Democrats also control all but two county offices. The lone Republican on the county council is Tom DiBello, and Merry Woods serves as the GOP representative on the Jury Selection Commission.

Despite those challenges, Republicans remain confident about their chances across the region.

Galko attributed the voter registration trends to Pennsylvanians feeling increasingly alienated from the Democratic Party.

“They wake up in the morning and realize this is not the party their grandparents or parents belonged to,” he said. “This is a totally different party with totally different principles, and they don’t identify with it anymore.”
