When President Donald J. Trump held a televised cabinet meeting on Aug. 26, 2025, he proudly referred to a week-old report by the New York Times that found the Republican Party making tremendous gains in voter registration across the country, including in battleground states like Pennsylvania.
“The Republican Party picked up 4 million new people — 4 million. The Democrats have lost 2.5 million people. Other than that, they are extremely happy,” he said, under-reporting the actual GOP gains and over-reporting the other party’s losses. “No, they are very depressed.”
“They are very smart but they are the radical left and they are destroying our country,” he said several minutes later. “They won’t destroy it anymore. We picked up millions of people in the Republican Party and I think we will do well in the midterms.”
The New York Times report found that the GOP had registered 4.5 million additional voters in the 30 states that track registration by political party between 2020 and 2024, and that Democrats had lost ground to Republicans in every one of those states, losing 2.1 million voters in that same span.
Since then, however, there’s been a significant shift in Pennsylvania toward the Democratic Party.
Democrats lead in Pa. voter registration for 10 straight months
Consider this:
- Democrats have outgained Republicans in voter registration in 10 consecutive months, starting in October 2025.
- Between Aug 4, 2025, and Aug. 3, 2026, Democrats added 35,244 voters to the rolls, while Republicans picked up 3,537.
- Just once in the past seven months did Republicans gain voters: In March, when the GOP saw an increase of 609 voters. In that same month, Democrats added 4,697 voters.
- Only once between 2013 and 2025 have Democrats had a net gain in the number of existing voters who opted to switch parties. And at no time during that span did they outgain Republicans and independents among party-switchers. The year they gained was 2018, which like this year was the midterm election during a Trump presidency.
- In 2026, however, Democrats have a net gain of 6,322 previously registered voters, compared to net losses of 3,811 for Republicans and 2,511 for independent or third-party voters. More Republicans switched their registration to Democrat (14,479) than vice versa (13,951).
- Independents who opted to affiliate with a major party have also preferred the Democrats over the Republicans this year with 23,434 opting to become Democrats compared to 10,607 who chose the GOP.
Several factors could be driving the trend, including a commitment from the new Democratic Party of Pennsylvania chairman, Eugene DePasquale, who was elected in September 2025, to make voter registration a priority.
DePasquale said Democrats in recent years have worked to boost voter registration across the board, regardless of party affiliation. On the other hand, he said, Republicans have primarily focused on increasing their own rolls, and he argues that discrepancy helps explain why his party had lost ground in the commonwealth since the Obama era.
While he supports voter participation in general, DePasquale said a party’s job is to expand its own ranks, a strategy he’s championed since becoming chairman.
“I started directing our teams and our party apparatus to make sure that it was a priority, of registering Democrats,” he said.
Another factor is likely that Pennsylvania has a closed primary system and several key U.S. Congressional races, particularly in eastern Pennsylvania, had multiple Democrats vying to unseat vulnerable incumbent Republicans, according to Robert Speel, professor of political science at Penn State University’s Behrend campus in Erie County.
“There’s many mixed motivations involved,” Speel said. “Some people, just due to family histories, tend to prefer a certain party and may switch back and forth with family members. There also is the fact that sometimes in some races you have contested primaries in some parties and not in others, and people may switch temporarily.”
History lesson, political polling trend
And then there’s the fact that’s haunted most modern U.S. presidents: Only three times since the Civil War has the party of an incumbent president picked up seats in the U.S. House: 1934, 1998 and 2002.
Trump’s declining popularity in recent polls of Keystone State voters, a majority of whom have given Trump poor marks on issues like the economy and his handling of inflation and the war with Iran, also appears to be reflected in the voter registration trend.
“The numbers are obviously good news for Democrats,” Speel said. “They show potentially a diminished luster for Trump in Pennsylvania. The fact that Republicans were gaining in voter registration for much of the last decade was a signal that Trump was eventually going to win Pennsylvania in 2016 and 2024. The fact that Democrats in the past year have been the party making the gains in Pennsylvania indicates a diminished popularity of Donald Trump in Pennsylvania and nationwide.”
Trump might also be suffering because, “unless he unconstitutionally tries to run again in 2028,” he won’t be on the ballot as a presidential candidate again, Speel said.
Pa. Democratic Party has lost voters for years
However, the gains made by Democrats pale in comparison to what the party has ceded to the GOP since 2015.
Republicans were just 174,670 registered voters away from Democrats on Sept. 1, 2025. Now, overall registration separates the parties by 206,430 voters. There are now 3.84 million registered Democrats to just under 3.63 million Republicans.
Considering Democrats had an advantage of 992,651 voters over the GOP in 2015, James Markley says the party’s gains in 2026 don’t worry him much.
Markley is the executive director and spokesperson for the Pennsylvania Republican Party.
“The real story here is that in 2024, when Republicans in Pennsylvania had the best election of my lifetime,” Markley told the USA Today Network Pennsylvania on July 30. “Pennsylvania was called early on election night. We got Dave McCormick as a U.S. senator. We had all these pickups in Congress. And we had a lesser share of voter registration at that time than we do today. Since then, we have picked up tens of thousands of Republican voters across the commonwealth. So while the Democrats are registering a couple of people this year, I mean, really, it’s nothing crazy.”
On Aug. 3, when the Pennsylvania Department of State released its weekly update of voter registration data, Markley was quick celebrate a “historic milestone.” The party is now within 25,811 active voters of closing the gap with Democrats. The state lists the total number of registered voters, but also includes data on how many of those voters by party have fallen into inactive status.
The state designates a voter inactive if they haven’t voted in two consecutive federal elections and has not responded to a notification from their county elections office. They can still vote, but they’ll have to sign a form affirming their eligibility when they go to the polls.
The latest figures show that Democrats have 3,405,389 active voters to Republicans’ 3,379,578, and 437,330 inactive voters to the GOP’s 256,711. Markley noted in his Aug. 3 statement that the state party’s current leadership started with an active voter “deficit” of more than 100,000, but that number had fallen to just 56,001 as of July 27.
In the course of a week, some 55,241 registered Democratic voters were moved from active to inactive status. Republicans saw their active voters drop, too, by 23,832. The change is part of county elections boards’ regular maintenance of its voter rolls. By law, this kind of update must occur no later than 90 days before a federal election. Voter-roll maintenance typically occurs between May and July and happens because people move, die or change their registration. County boards either remove people from the rolls entirely or shift their status from active to inactive, according to the Department of State.
“Maintaining accurate voter registration lists is essential to ensuring free, fair, safe, and secure elections,” Secretary of the Commonwealth Al Schmidt, a Republican, said in a statement Aug. 5 after several Republicans misinterpreted the shift of voters from active to inactive status as a purge. “Pennsylvania’s county election officials follow carefully prescribed legal procedures to keep voter rolls current while protecting eligible voters from being improperly removed. Routine voter list maintenance is an important part of administering elections and should not be misconstrued as any attempt to disenfranchise eligible voters.”
Republicans, however, are still celebrating the narrowing gap of active voters between the two parties as a victory.
”This milestone is the direct results of thousands of volunteers, county parties, and grassroots activists who refused to sit back and let Democrats spread their socialist agenda in our commonwealth,” Markley said in a statement. “All of the hard work Republicans have continued to pour into the 2026 election cycle has brought us one step closer to our ultimate mission of turning Pennsylvania into a permanent red state.”
Jack Doyle, spokesman for the Pennsylvania Democratic Party, said the GOP is attempting to change the conversation about his party’s recent success.
“Republicans can try to spin the numbers all they want,” he said, “but they can’t change the fact that they are running on a toxic agenda that Pennsylvanians all across the commonwealth are going to reject again this November.”
