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.

As a Pennsylvanian, one issue I was looking out for in the attorney general primary was discussion of legalizing marijuana. While the candidates did discuss it at their April 4th debate, it didn't come up much in the conversation around the race. Despite advocating legalization during his term as auditor general, the issue doesn't appear at all on DePasquale's campaign site. That may be because Pennsylvanians' views on legalization have been evolving.

According to the annual Muhlenberg College Pennsylvania Health survey, support for legalizing recreational marijuana in Pennsylvania has decreased in the last few years. In the 2021 survey, 58 percent of Pennsylvanians said they supported legalizing the use of marijuana "for any purpose," and 26 percent opposed legalization, a margin of 32 points. In the years since, the margin has steadily decreased, and in the 2024 survey conducted in February and March, 49 percent said they supported legalizing marijuana, while 31 percent opposed, a margin of 18 points.

Not all of these voters are necessarily opposed to legalization, though: The share of Pennsylvanians who express indifference about legal weed has also grown, with 20 percent saying they "neither favored nor opposed" legalizing marijuana in 2024, compared to 14 percent in 2021.

ABC News reports that Eugene DePasquale is projected to win the Democratic nomination for Attorney General. The only candidate from Western Pennsylvania, he overcame a fundraising advantage held by his opponents. DePasquale made a name for himself as a state auditor general and has promised to prosecute hate crimes against LGBTQ+ people, protect abortion, and other issues.

As I mentioned earlier, only two Republican women are running in House races today, compared to 15 Democratic women. And only one woman, Maria Montero in the 7th, is running in a seat where the party could be competitive in November. Pennsylvania has slightly below average female representation in their state legislature (which is just 32 percent female), and they've never had a female U.S. senator or governor (of any party). A state's history of electing women to political office is actually a pretty good predictor of electing more women in the future. Research indicates that once a state has elected a woman to a particular office, future female candidates are more likely to be successful in seeking that same office. Experts suggest this is due to increased familiarity and acceptance of women in political leadership and the establishment of support networks and resources for female candidates.

ABC hasn't made a projection in Montero's race yet, but The Associated Press has already projected it for state Rep. Ryan Mackenzie. Per the latest results, with 50 percent of the expected vote reporting, Montero trails, with 28 percent of the vote to Mackenzie's 43 percent and business owner Kevin Dellicker's 30 percent.

The war between Israel and Hamas in Gaza has paved the way for some bitter Democratic primary fights in 2024. Among those most critical of Israel's actions in the conflict has been The Squad, an informal group of around nine progressive Democrats who often clash with their party's establishment. Of that cohort, Rep. Summer Lee of Pittsburgh is the first to face a contested primary in 2024 — but she won't be the last. At least four members, including Lee, have potentially significant primary opposition in part because of their vocal denouncements of Israel — although increasingly negative views of the Middle East nation's actions among the Democratic base means the conflict may not be as helpful to The Squad's challengers as some may have expected.

Should Lee survive, she would join Reps. Greg Casar of Texas and Delia Ramirez of Illinois among those who've won renomination (Casar and Ramirez faced no opposition in their March primaries). But some members with primaries later this summer may have problems, especially the two who are arguably most endangered: New York Rep. Jamaal Bowman and Missouri Rep. Cori Bush. For one thing, they've each been outraised by their leading challengers, and they both have potential scandals that could derail their reelection efforts. Last fall, Bowman pulled a fire alarm in a Capitol office building right before a vote, which resulted in him paying a fine and receiving a censure from the House. And Bush faces investigations by the Department of Justice, Federal Election Commission and House Ethics Committee into alleged misuse of funds to pay her security team, including payments to her husband as part of that team.

Beyond those two, Minnesota Rep. Ilhan Omar may be the other Squad member who could have some trouble. Two years ago, she defeated former Minneapolis City Council member Don Samuels by just 2 percentage points in the Democratic primary; now Samuels is back for a rematch, although Omar has already raised more than twice as much as the $2.4 million she'd brought in by the time of the 2022 primary>. Otherwise, there are few signs that New York Rep. Alexandria Ocasio-Cortez, Michigan Rep. Rashida Tlaib and Massachusetts Rep. Ayanna Pressley will have difficulties. Ocasio-Cortez does have a challenger, but his largely self-funded effort pales in comparison to Ocasio-Cortez's campaign war chest, while Tlaib's little-known opponents only just filed for the race and haven't reported raising any money. Pressley, meanwhile, has no primary opposition ahead of Massachusetts's May 7 candidate filing deadline.
