We’re barely into the 2024 Senate cycle, and already some Republicans
are feeling a sense of deja vu. 

In a new must-read, our Holly Otterbein attended a rural Pennsylvania
rally for Doug Mastriano, the “state’s most MAGA Republican” who also
won its gubernatorial primary last year only to lose the general
election by double digits to Democrat Josh Shapiro. 

Her biggest takeaway: Despite that huge loss, Pennsylvania Republicans
aren’t ready to toss Mastriano overboard as he mulls a challenge to
veteran Democratic Sen. Bob Casey Jr.

“Establishment Republicans have found a silver lining amid the grimness
[of 2022]: Perhaps there will be a reckoning,” she writes. “Even diehard
supporters of former President Donald Trump, they’ve reasoned, are
finally sick of losing. … In this corner of the political world in
Pennsylvania, it’s the establishment — not the MAGAverse — that needs
course-correction.”
