In Pennsylvania's 10th District, where several Democrats were in today’s primary, former evening news anchor Janelle Stelson is currently leading with 48 percent of the expected vote in. Stelson has backing from EMILY’s List, which is historically a good sign. According to our analysis of the 2022 primaries, 85 percent of candidates endorsed by EMILY’s List’s in open primaries won their races. Interestingly, three candidates in open primaries endorsed by EMILY's List in California did not advance to the general election, which will bring down their success rate. But we'll need to wait and see how EMILY's List candidates do overall this cycle.

As I mentioned earlier, I'm tracking how anti-abortion Republicans are doing tonight. As Mary said, most Pennsylvanians support legal abortion, and it's shaping up to be a big issue in November. Three of the races I'm tracking are uncontested, and so we already have projected winners. Two incumbents, Rep. Scott Perry, who has six Democrats running to face off against him, and Lloyd Smucker, whose Democratic opponent pilot Jim Atkinson is also uncontested in the primary, are among the group. Aaron Bashir, a mathematics teacher at a community college and accountant for the city of Philadelphia, is the only Republican running to face off against incumbent Democrat Brendan Davis in the fall. He lost against Davis in 2022.

In the 10th District around Harrisburg, we now have early votes in from across all three counties in the district, representing almost half of the expected primary vote. This race doesn't look particularly close, either, as Stelson leads with 46 percent, followed by O'Brien with 21 percent and Daniels 13 percent. Hard to see Stelson losing that kind of edge at this point. The winner will face Rep. Scott Perry, the former House Freedom Caucus chair.

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.

In Bucks County, just outside Philadelphia, steadfast moderate Republican Rep. Brian Fitzpatrick is facing a primary challenge from the right for his seat in the 1st District. Mark Houck is an anti-abortion activist and head of a nonprofit ministry group for Catholic men who made a name for himself as a bit of an anti-abortion martyr when he was charged with assault (but found not guilty) after shoving a 72-year-old clinic volunteer in 2021 while protesting outside a Planned Parenthood in Philadelphia. Fitzpatrick was first elected to Congress in 2016, succeeding his brother (the late former Rep. Mike Fitzpatrick). He's faced a primary challenger in every election since, but has always triumphed.

Fitzpatrick has made a reputation for himself locally and on the Hill as a moderate who keeps his distance from the MAGA right. He's got a track record of bipartisanship and moderate policy stances in Congress and refused to endorse Doug Mastriano, the GOP's far-right nominee for governor in 2022. He even snubbed Trump's visit to Bucks County earlier this month. His position on abortion has been a bit less clear — there's no mention of abortion on his reelection campaign website — though he has drawn ire from abortion rights groups. He's certainly no culture warrior like Houck, whose organization opposes "same-sex attraction disorders" and pornography, and works to shut down "sexually oriented businesses."

But whoever wins this primary isn't necessarily a shoe-in for the seat. Fitzpatrick or Houck will be going up against Democrat Ashley Ehasz. Fitzpatrick defeated Ehasz in 2022 by 10 percentage points, but the area is purple and shows signs of shifting blue — Biden won the district in 2020, and Democrats swept all five seats up for grabs in a recent local school board election. Fitzpatrick is the lone Republican in the districts surrounding Philadelphia, though his is the whitest of those collar counties and the conservative areas of the county are increasingly polarized. That could mean Fitzpatrick faces serious competition from Houck in the party primary, but Houck's far-right leanings could tilt the general election contest toward Democrats if he makes the ballot in November.
