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.

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.

Today's House primaries in Pennsylvania feature a dearth of Republican women: Of the 19 GOP candidates running today, just two are women. To get a sense of how lopsided this is, as we saw earlier, 12 out of the 25 candidates running for the U.S. House on the Democratic side are women.

Since about the mid-1990s, Democrats have been electing more women to Congress than Republicans, due in large part to more Democratic women running. That said, in both the 2020 and 2022 cycles, more Republican women ran in primaries than ever before. But what's more important to electing more women is where women are running, and if they are competing in places they can win in November.

In Pennsylvania's 5th District, Alfeia Goodwin is the only Republican candidate on the ballot, so in that sense she's set up to succeed in her primary! However, in November she'll face incumbent Rep. Mary Gay Scanlon, who handily won reelection in 2022 and is almost certain to hold the safe blue district. This race illustrates the "sacrificial lamb" phenomenon where a candidate runs unopposed in the primary for a losing seat. There's from political science that Republican women are sacrificial lamb nominees more often than Democratic women.

Things are more interesting in the 7th District race Kaleigh just previewed, where the Democratic incumbent, Rep. Susan Wild, barely eked out a win in 2022 against a female Republican nominee, Lisa Scheller. Scheller isn't running for the GOP nomination this cycle, but another woman, attorney Maria Montero, is on the ballot today against state Rep. Ryan Mackenzie and Kevin Dellicker, a veteran and cybersecurity business owner.

Although this is a seat Republicans are targeting in November, Trump hasn't endorsed anyone in the primary race. But a Trump surrogate, former presidential candidate Vivek Ramaswamy, has been . She hasn't received an endorsement from any of the GOP women's groups we are tracking (VIEW PAC, Maggie's List, E-Pac, and Winning for Women). That said, E-Pac, which was started by Trump acolyte Rep. Elise Stefanik, hasn't made any primary endorsements this cycle, despite its stated mission to elevate women in primaries.
