Pathologist Margaret Burke Flips Montco's 147th District In Historic, Razor-Thin Win

Molecular pathologist Margaret Burke, a political newcomer, has flipped Montgomery County's 147th legislative district blue for the first time in history.

Unofficial results give her a razor thin margin of victory over incumbent GOP State Rep. Donna Scheuren, 15,904 to 15,687, a difference of just 217 votes.

“I am honored that the voters of District 147 have put their faith in me to lead in Harrisburg," Burke said Wednesday. "This is what we worked for: all the door knocking, all the conversations, it was all to make sure that my leadership is built on genuine connection with this district and the priorities of all of you who make it such a special place.

The seat was one of several in the state legislature which Democrats flipped on Tuesday as they retained control of the house and gained control of the senate, giving them a "trifecta" of leadership in state government for the first time since 1993.

Scheuren won this seat by some 7,000 votes over Al Leach in 2024. And in the 67 years that Republicans have held the seat, it's never seemed to be in particular peril from the left.

The district covers the most rural sections of Montgomery County, stretching out to the border with Berks County, including Douglass, Lower Frederick, Lower Salford, New Hanover, Upper Frederick, Upper Pottsgrove, and Upper Salford, along with part of Franconia. It's an area that's been solidly pro-Trump in the past three presidential elections.

It was not the only long-held GOP stronghold in Montgomery County that fell on Tuesday. The 24th senatorial district, which also had never been won by a Democrat, was flipped by Chris Thomas.

Scheuren faced the same problems of national momentum as State Sen. Tracy Pennycuick, the incumbent in the 24th. But the 147th race was also marked by additional vitriol and controversy over Scheuren's voting record and each candidate's stance on how best to protect the region from data center development.

Scheuren claimed that Burke's team had spread misinformation over her data center positions, saying that her "no" vote on protective legislation was due to concerns over where final authority would lie, not the protective measures.

"My position has been clear and consistent: protect local control. Require data centers to provide their own power. Ensure local taxpayers receive the financial benefits," Scheuren said. "My opponent’s willingness to attack without understanding the legislation demonstrates a troubling lack of judgment and raises serious questions about whether she possesses the skills necessary to effectively represent our communities."

Burke said in October that Scheuren's votes were votes against transparency.

"Young people are worried for their futures, and we need to do better," Burke said. "I’ll vote for guardrails on data centers that keep our energy bills low and protect our water and environment."

Data centers figured large in Tuesday's elections, with some of the most vocally anti-development candidates like State Sen. Katie Muth winning by the largest margins.
