From the article:
The liberal comedian then asked Fetterman whether his shift in various policies had anything to do with his recovery from his 2022 stroke, asking if his near-death experience had given him a “freedom.”
“Absolutely,” Fetterman responded. “There’s a line from the first ‘Batman,’ Joker’s like ‘I’ve been dead once already. It’s very liberating.'”
“It’s freeing in a way. And I just think after beating all of that, I just really [want to] be able to say the things that I have to really believe in and not be afraid of if there’s any kind of blowback.”
So basically yes, the stroke made him a Republican. Pathetic and disappointing, but all too predictable.
If that brain damaged asshole had any integrity he’d resign because he’s no longer capable of doing the job he was elected to do.
