Fetterman calls Trump's support in Pennsylvania 'astonishing': 'You can see the intensity'

Fetterman continued, "I was doing an event in Indiana County. Very, very red. And there was a superstore of Trump stuff, and it was a hundred feet long. [There were] dozens of T-shirts and hats and bumper stickers and all kinds of, I mean, it's like, Where does this all come from? It's the kind of thing that has taken on its own life. And it's like something very special exists there. And that doesn't mean that I admire it. It's just - it's real."

"And now [Elon] Musk is joining him," Fetterman said. "I mean, to a lot of people, that's Tony Stark. That's the world's richest guy. And he's obviously, and undeniably, a brilliant guy, and he's saying, Hey, that's my guy for president. That's going to really matter."

Fetterman said he was "alarmed" when Musk began showing up on the campaign trail for Trump and said he's a "bigger star than Trump" in "some sense."

"Endorsements, they're really not meaningful often, but this one is, I think," Fetterman said. "That has me concerned."

Fetterman told the New York Times that he does not believe the 2024 election will come down to "a certain policy" but will instead come down to the "stark choice" between Harris and Trump. 

"It's visceral," Fetterman said. "And that's why the people that are left that haven't made up their decision are going, you know, what do I want for the next four years? And I do believe enough people will choose Harris. But it's going to be much, much closer than anyone would want."
