Doug Mastriano, the far-right state senator who attended the Jan. 6, 2021, insurrection and has been at the center of efforts to overturn the fair results of the 2020 presidential election, won the Republican primary for governor in Pennsylvania on Tuesday raising the prospect of an insurrectionist being governor of a key battleground state for the 2024 presidential contest.

Mastriano led the nine-person field with just over 40% of the vote on Tuesday when NBC News and The Associated Press called the race. He was beating his closest opponent, former U.S. Congress man Lou Barletta, by almost 20 points.

He received a boost three days before the election from former President Donald Trump, who endorsed Mastriano and thanked him for his commitment to the lie that Trump didnt lose to President Joe Biden.

There is no one in Pennsylvania who has done more, or fought harder, for Election Integrity than State Senator Doug Mastriano, Trump said in a statement. He has revealed the Deceit, Corruption, and outright Theft of the 2020 Presidential Election, and will do something about it.

After Bidens victory was certified in Pennsylvania in November 2020, Mastriano introduced a resolution that would have had the Republican-controlled state legislature overturn the results Biden won there by 80,000 votes and instead appoint electors who would declare Trump the winner.

The resolution failed but further endeared Mastriano to the world of MAGA and to Trump himself, with whom Mastriano claims to be in regular contact.
