Last Updated: May 17, 2022, 10:15 PM EDT

Voters were heading to the polls Tuesday for primary elections in Pennsylvania, North Carolina, Kentucky, Idaho and Oregon amid a midterm season that will test the endorsement power of both President Joe Biden and former President Donald Trump.

While Trump wasn't successful across the board, at least 22 of his 25 endorsed candidates for Senate, House and governor (mostly in noncompetitive races) won Tuesday night, according to FiveThirtyEight.

Chris Deluzio projected to win primary for Rep. Conor Lamb's seat

ABC News projects that Chris Deluzio will win the Democratic primary for Pennsylvania's 17th Congressional District.

Deluzio is a veteran and voting rights attorney and beat out LGBTQ rights advocate Sean Meloy for the Democratic nomination in the seat currently held by a Democrat. The district Deluzio ran in is being vacated by Rep. Conor Lamb, who ran for Senate in the state but fell short to Lt. Gov. John Fetterman in the Democratic primary earlier Tuesday night.

Mastriano projected to win GOP gubernatorial primary in Pennsylvania

In the Pennsylvania gubernatorial Republican primary, ABC News projects state Sen. Doug Mastriano will win, beating out his closest primary rival, former Rep. Lou Barletta.

Mastriano, a retired Army colonel and long proponent of "the big lie," gained former President Donald Trump's endorsement only three days ago. Mastriano attended Trump’s Jan. 6 rally in Washington and falsely claimed in December 2020 that "cheating and fraud happened in our state." As a state senator, he also attempted to launch a forensic "audit" of the state’s election results, similar to the partisan inquisition that took place in Arizona. It failed to find any evidence of widespread fraud.

The race is especially significant since the governor of Pennsylvania gets to name the secretary of state -- the state's chief election official, charged with overseeing elections.

The House Jan. 6 committee has subpoenaed Mastriano, given that he was in communication with Trump on Jan. 6, but neither he nor the committee has confirmed whether he complied with the order.

Attorney General Josh Shapiro, running unopposed for the Democratic nomination for governor, has called Mastriano "the most extreme and dangerous GOP candidate." The two will face off in November.

She opened by "addressing the elephant in the room," which is that "my husband John Fetterman is not in the room," and said Fetterman would be "back on his feet in no time."

"This race we’re running is a race for the future," she said to a warm audience. "It’s a race for every job that has been lost, every factory that has been closed, every cost that has been rising, every worker that can’t keep up. It’s a race for a better Pennsylvania."

She also mentioned two issues her husband raises at almost every stop: a commitment to legalizing marijuana and to eliminating the Senate filibuster.

Biden celebrates Fetterman's projected win

President Joe Biden didn’t endorse in the race, but the son of Pennsylvania celebrated John Fetterman's win in the state's Senate Democratic primary on Tuesday.

"John Fetterman understands that working class families in Pennsylvania and across the country have been dealt out for far too long. It’s time to deal them back in, and electing John to the United States Senate would be a big step forward for Pennsylvania’s working people," the president wrote.
