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.

In tonight's primaries, voters aren't just deciding on federal candidates for November's general election; they're also setting up the battles for control of the state House and Senate. In 2022, Democrats won the governorship, and they currently hold a one-vote majority in the House they've struggled to maintain through a series of special elections. The party is looking to expand that House majority and gain control of the Senate for a trifecta by targeting opportunities (and defending some vulnerable seats) in the purple areas of this purple state. And, of course, Republicans want to keep their Senate majority, which they've held for 30 years, and take back the House.

Republicans have a six-vote majority in the state Senate, so Democrats need to pick up at least three seats for a tie, which could be broken by Democratic Lt. Gov. Austin Davis. Half the chamber is up for election this cycle. Among the handful of key races, Democrats will be defending an Allegheny County seat and challenging Republicans for a Harrisburg-based seat that are both opening up because of retirements. In both districts, each party is holding a contested primary today and redistricting could give Democrats a boost in November. Democrats are also challenging Republican incumbents in two seats that flipped to red in 2016 and 2020; one will hold a competitive Democratic primary today between Erie County Democratic Party Chair Jim Wertz and former Sen. John Fetterman staffer Selena King.

In the House, the hot primary action will largely be on the Democratic side, as the party's more progressive and centrist flanks face off in districts around Philadelphia and Pittsburgh. In West Philadelphia, Rep. Amen Brown is defending his seat against two challengers, Sajda Blackwell, whose family has a history in area politics, and progressive community activist Cass Green. Brown ran unsuccessfully for mayor on a tough-on-crime stance, and has sided with Republicans in criticizing progressive Philly DA Larry Krasner. Elsewhere in the city, three incumbents endorsed by progressive group Reclaim Philadelphia are facing challengers of their own. And in the Pittsburgh area, state Rep. Abigail Salisbury, who stepped into U.S. Rep. Summer Lee's former seat, is facing a challenge from Ashley Comans, a progressive school board member who lost to Salisbury last year and is endorsed by Lee herself.

Tonight's results will have an effect on their party's chances to hold onto the state House majority in November, and also the direction the Democratic party may try to take should it seize a trifecta.
