All of today's congressional primary contests where women were running have been projected, according to ABC News. There aren't too many surprises, here. In most places where Democratic women lost, another woman won (e.g. Summer Lee fended off Bhavini Patel in the 12th; Janelle Stelson prevailed over Shamaine Daniels in the 10th). The exception is Tracey Gordon who was mounting a challenge to Democratic incumbent Dwight Evans in the 3rd. For the GOP, in the 7th, Maria Montero would've advanced to a competitive November race, but failed to win. In the 5th, Alfeia Goodwin was uncontested, but she will face an uphill battle in that blue district.

Tonight I've been tracking anti-abortion Republicans, and there was one notable loss: Houck, a far-right anti-abortion activist, lost to moderate incumbent Fitzpatrick. In most of the other races, anti-abortion Republicans ran unopposed, and in Pennsylvania's 7th, all three Republican primary candidates were on our list. As Kaleigh noted, Mackenzie is the projected winner in that race to take on Wild in what's expected to be one of the most competitive House races this fall.

Meredith called it with the Matty Healy reference wrapped in a namedrop of "The Starting Line" (who subsequently thanked T Swift for the shoutout). In her song “The Black Dog,” Swift sings about an ex, asking how he can not miss her when in a pub and somebody plays "The Starting Line," but "she’s too young to know this song.” That said, Swift has dropped a political reference or two before, though more general. She uses the term “also ran” on this latest album and has the cutting line “did you hear my covert narcissism I disguise as altruism like some kind of congressman?” in “Anti-Hero,” her big single from her last album.

For kicks, I'll guess D, Kaleigh. If the song is about corruption, Fumo would be a good reference: In 2009, he was convicted of 137 corruption counts for various schemes, defrauding various institutions and obstruction of justice.

Happy primary day to those who celebrate! (That's us, fellow Pennsyvlanians.)

The Keystone State is already in the public eye this election cycle, as it's expected to be a battleground state for both the presidential race and a critical U.S. Senate race between incumbent Democratic Sen. Bob Casey and Republican David McCormick. And there are consequential races down the ballot, too: Several competitive U.S. House races could impact the balance of the House majority, while Democrats are hoping to compete for control of both chambers of the state legislature to earn their first state government trifecta in more than 30 years.

And while the candidates for president and Senate are set, today's primary contests will determine just who's on the ballot from each party in those key down ballot races. Tonight, we're closely tracking a handful of significant U.S. House races, including progressive Rep. Summer Lee's bid to hold off a more moderate challenger; moderate Republican Rep. Brian Fitzpatrick's challenge from the hard right; and a three-way GOP primary to decide who will face off against Rep. Susan Wild in one of the most competitive House races this fall. We've also got our eyes on some hotly contested primary contests for statewide offices like attorney general and a number of spicy state legislative races.

As usual, we'll be here to guide you through it all with the latest results and analysis throughout the evening. We should start seeing results come in shortly after polls close at 8 p.m. Eastern. Thanks for joining us!
