As Geoffrey just mentioned, Summer Lee is leading her primary challenger, Bhavini Patel, in the 12th District. Political science research actually finds that incumbent women in Congress are more likely to face challengers than incumbent men. This is due to several factors, such as a history of women's underrepresentation which gives the impression that female incumbents are more vulnerable; this leads to higher quality challengers, too.

The three Republicans running for the chance to defeat Rep. Susan Wild in Pennsylvania's competitive 7th District are all anti-abortion. With 26 percent of the expected vote in, state Rep. Ryan Mackenzie has a lead with 42 percent of the vote. Mackenzie has told a local news station that the issue is best left to the states because there's no consensus at the federal level. In Pennsylvania, he's voted for a constitutional amendment saying there's no right to taxpayer-funded abortions.

Lee now leads Patel 57 percent to 43 percent in Pennsylvania's 12th District Democratic primary, with 57 percent of the expected vote reporting. Allegheny County has begun reporting votes cast on Election Day (that is, not early or by mail), and Lee is winning about 3 in 4 of those votes so far. That edge may not last, but considering Lee leads 55 percent to 45 percent among the early and mail votes, she doesn't need much to hold her lead. A Patel comeback looks quite unlikely. In fact, Decision Desk HQ projected the race for Lee a few minutes ago. We're still waiting for a projection from ABC, though.

As expected, given that both were unopposed, ABC News has projected that both Republican David McCormick and Democratic Sen. Bob Casey will win their respective primaries and advance to the general election for Pennsylvania's U.S. Senate seat this November. Casey starts out with a slight advantage in both fundraising and the polls, but most analysts are still predicting a tight race.

That’s right, Meredith, and as I mentioned earlier, Fitzpatrick beat Ehasz by 10 points in 2022, but there are signs that this race could be tighter. It’s a purple district that has seen some shifts to the left, namely some recent school board elections. Voters flipped the Central Bucks School District from majority Republican to majority Democratic in an election last year, and Democrats swept the Pennridge School Board election. Of course, school board elections have their own quirks, particularly with some of the identity politics issues that have come to a head in recent years, but we could see a similar friction emerge with abortion as a hot-button issue in the general. While Fitzpatrick is hardly an anti-abortion activist, it’s an area where he hasn’t been as clearly moderate (he’s voted for abortion bans, for example, and his campaign website avoids the issue entirely), and Ehasz has a clear advantage on this front. Of course, Fitzpatrick’s incumbency and the more conservative reaches of the district could certainly be enough to keep him in his seat, but I’d be willing to bet it will be by a slimmer margin than last time, if he manages to pull it off.
