Oh No

I think it's been forgotten, mostly, that Fetterman had delusions of running for president, not that long ago. I'm not sure if he still had those delusions before the election (doubtful), but now whatever path he had to remaining relevant is gone.

Leaving aside the specifics of the man, I do think it is much much much more difficult to be the mavericky party switcher (either direction) than it once was. Fetterman can't out-MAGA someone in a PA Republican primary, even if Republicans don't hate him.
