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.

We'll be keeping an eye on how candidates of color perform in tonight's House primaries. Racial diversity in Congress has steadily grown over the past two decades, with nonwhite representatives skewing heavily Democratic. In today's races, six candidates of color are running in Democratic primaries compared with four Republican hopefuls.

In the Pittsburgh-area 12th District, Democratic Rep. Summer Lee is seeking a second term after winning a fiercely contested primary by less than 1,000 votes in 2022, when she became the first Black woman to be elected to Congress from Pennsylvania. This year, she faces a primary challenge from Bhavini Patel, an Indian-American small business owner and Edgewood Borough Council member. Patel has aligned herself as a more moderate, pro-Israel foil to Lee, a member of The Squad — a group composed entirely of young progressives of color — who was heavily targeted by AIPAC in her first congressional bid.

Democratic Rep. Dwight Evans, another Black incumbent, is facing a primary challenger in Tracey Gordon, former Philadelphia register of wills. The majority Black, deep-blue 3rd District spans much of central and west Philadelphia, where tonight's winner is all but guaranteed to win the seat in November. The scandal-embroiled Gordon is an underdog candidate here, though she has some experience with that: She defeated a 40-year incumbent in the 2019 primary on the way to becoming the city's register of wills, but lost her reelection bid last May.

A six-way Democratic primary in the 10th District includes Harrisburg City Council member Shamaine Daniels and Blake Lynch, a former local radio executive. Daniels was the Democratic nominee in 2022, but was defeated by Republican Rep. Scott Perry, the former chair of the hard-right House Freedom Caucus. Whoever wins tonight will face Perry in November.

On the Republican side, attorney Maria Montero is one of three Republicans vying to face 7th District Democratic Rep. Susan Wild in what is anticipated to be a highly competitive general election. Entrepreneur Aaron Bashir, former Army chaplain Alfeia Goodwin and business executive James Hayes are each running unopposed in today's Republican primaries in their districts. All three are assured a spot on the ballot in November, but face long odds against Democratic incumbents in solidly blue districts.
