Doug Mastriano has won the Republican nomination for governor in Pennsylvania, based in part on a strong in-person election day performance.

The Franklin County state senator defeated seven other candidates for the nod, including former Hazleton mayor Lou Barletta, former U.S. attorney Bill McSwain, and Delaware County businessman Dave White.

A number of Republican Party leaders made late moves in an attempt to negate the momentum that Mastriano showed in the last weeks, but to no avail,

Mastriano, who received the endorsement of former president Donald Trump last Saturday, has been a strong supporter of Trump’s debunked claims about the 2020 election and helped organize transportation and attended the January 6 insurrection at the capitol.

He will meet Pennsylvania attorney general Josh Shapiro, the Democratic nominee, in the general election.
