State Sen. Doug Mastriano, who rose to prominence by pushing baseless accusations of election fraud in 2020 and scored a last-minute endorsement from former President Trump, won the Republican nomination for Pennsylvania governor on Tuesday, per the AP.
Why it matters: Trump's endorsement has continued to be powerful among the Republican base, and he picked the state senator because he "has been with me right from the beginning, and now I have an obligation to be with him."
