Doug Mastriano rules out 2024 Senate run in Pennsylvania

Doug Mastriano, a far-right state senator who lost in Pennsylvania's gubernatorial contest last fall, announced that he will not run for Senate in 2024. Republicans are trying to knock off Sen. Bob Casey, whose re-election bid in the battleground state will play a key role in Democrats' effort to keep their slim majority in the Senate next year. Many Republicans are looking to Dave McCormick, a businessman who narrowly lost a GOP Senate primary last year to celebrity doctor Mehmet Oz.
