ABC News reports that Lee is projected to defeat Patel in the 12th District Democratic primary. She currently leads 59 percent to 41 percent with 73 percent of the expected vote reporting. Lee is the first member of the progressive group of House members known as The Squad to face a primary challenge this cycle, but she's turned back her opposition. She will be easily favored to win in November in a seat that Biden would've carried by 20 points in 2020.

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.

In the 7th District in eastern Pennsylvania, hometown boy and state Rep. Ryan Mackenzie is leading the GOP primary to face Democratic Rep. Susan Wild this fall. With 65 percent of the expected vote reporting, Mackenzie has 42 percent, while business owner Kevin Dellicker has 31 percent and attorney Maria Montero has 27 percent. While ABC News is not yet reporting a projection, the AP has projected Mackenzie to take the W, and Wasserman saw enough 45 minutes ago. The winner of this primary will attempt to unseat Wild, a three-term member of Congress who held onto her seat by just 2 points in 2022. It's set to be one of the most competitive House races in the country this fall.
