In the 12th District Democratic primary, incumbent Lee leads challenger Patel 55 percent to 45 percent after Allegheny County (Pittsburgh) reported a big chunk of early votes just after polls closed. On the one hand, this shows Patel isn't that far behind Lee and could be in the race. On the other hand, Lee actually lost the mail/early vote in the 2022 primary here when she first won this seat, 51 percent to 31 percent, but this time around she leads it. And since about 90 percent of the primary vote will come from Allegheny (the rest from Westmoreland next door), Lee has to be seen as a favorite at this point.

In the 1st District, GOP Rep. Brian Fitzpatrick is well ahead of his challenger from the right, anti-abortion activist Mark Houck. With 20 percent of the expected vote reporting, Fitzpatrick has 83 percent to Houck’s 17 percent. In fact, the Associated Press has already called this race and projected Fitzpatrick to win. ABC News, however, has yet to make a projection, so hang tight!

In Pennsylvania, as in many states around the country, voters name the economy as the most important issue facing the state. In a mid-March Emerson College/The Hill survey, 36 percent of respondents said "the economy (jobs, inflation, taxes)" was the most important issue facing Pennsylvania. The next most chosen issue was crime (12 percent), followed by immigration and "threats to democracy" (11 percent each) and healthcare (9 percent).

Republicans were particularly concerned about the economy and immigration, with 47 and 21 percent selecting those two issues, respectively, and no other issue chosen by more than 9 percent of Republican voters. Democrats also selected the economy first, but with less gusto: 27 percent said the economy is the most important issue, followed by threats to democracy (16 percent), healthcare (15 percent) and crime (13 percent).

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.

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.
