As expected, given that both were unopposed, ABC News has projected that both Republican David McCormick and Democratic Sen. Bob Casey will win their respective primaries and advance to the general election for Pennsylvania's U.S. Senate seat this November. Casey starts out with a slight advantage in both fundraising and the polls, but most analysts are still predicting a tight race.

In Pennsylvania's 10th District, where several Democrats were in today’s primary, former evening news anchor Janelle Stelson is currently leading with 48 percent of the expected vote in. Stelson has backing from EMILY’s List, which is historically a good sign. According to our analysis of the 2022 primaries, 85 percent of candidates endorsed by EMILY’s List’s in open primaries won their races. Interestingly, three candidates in open primaries endorsed by EMILY's List in California did not advance to the general election, which will bring down their success rate. But we'll need to wait and see how EMILY's List candidates do overall this cycle.

As I mentioned earlier, I'm tracking how anti-abortion Republicans are doing tonight. As Mary said, most Pennsylvanians support legal abortion, and it's shaping up to be a big issue in November. Three of the races I'm tracking are uncontested, and so we already have projected winners. Two incumbents, Rep. Scott Perry, who has six Democrats running to face off against him, and Lloyd Smucker, whose Democratic opponent pilot Jim Atkinson is also uncontested in the primary, are among the group. Aaron Bashir, a mathematics teacher at a community college and accountant for the city of Philadelphia, is the only Republican running to face off against incumbent Democrat Brendan Davis in the fall. He lost against Davis in 2022.

In the 10th District around Harrisburg, we now have early votes in from across all three counties in the district, representing almost half of the expected primary vote. This race doesn't look particularly close, either, as Stelson leads with 46 percent, followed by O'Brien with 21 percent and Daniels 13 percent. Hard to see Stelson losing that kind of edge at this point. The winner will face Rep. Scott Perry, the former House Freedom Caucus chair.

With Biden and Trump having sewn up their party's nominations, the Pennsylvania presidential primary is an afterthought today. But the Keystone State will definitely be at the forefront of the general election campaign: In 2016, Trump carried it by 0.7 percentage points, and in 2020, Biden won it by 1.2 points, making Pennsylvania one of the most competitive states in the country. And with 19 electoral votes, the state is the largest battleground-state prize in the Electoral College (if you don't include Florida, which has 30 electoral votes but may have a GOP lean now).

Early polling for the November election confirms the expectation that Pennsylvania will once again feature a hard-fought campaign. 538 hasn't released its general election polling averages yet — they're coming very soon — but Trump and Biden are running close to even in recent polls. The most recent one we have, a mid-April survey from Beacon Research/Shaw & Co. Research/Fox News, found them tied at 48 percent, with Trump edging ahead by 2 points when third-party candidates like Robert Kennedy Jr. were included as options.

Given Pennsylvania's importance, it's no surprise that both Biden and Trump are heavily focused on it. Biden just completed a campaign swing through the state last week, including a stop at his childhood home of Scranton. Just days earlier, Trump held a campaign rally in the Lehigh Valley ahead of the start of his hush-money trial in New York City. There'll certainly be more of that in Pennsylvania — and a gazillion attack ads on television and digital airwaves — before Election Day.
