Sen. John Fetterman, D-Pa., told CBS News on Saturday that a Democratic takeover of the U.S. Senate this November is "entirely possible" — then pointedly declined to say whether he will still be a Democrat, or even still in the Senate, by the time voters find out. Speaking at the Texas Tribune Festival in Austin with CBS News' Major Garrett, Fetterman gave no clean answer on his own political future, including whether he'll seek reelection when his term ends in 2028. "Let's revisit after the midterm," he said.

Republicans currently hold a 53-47 Senate majority, meaning Democrats need a net gain of four seats on Nov. 3 to flip control — a tall order on a map once considered brutal for the party, with 35 seats in play nationwide. But cracks have opened in recent weeks: an internal Marist poll has Iowa Democrat Josh Turek running eight points ahead in a race Republicans once expected to hold easily, and NBC News' polling average now shows Democrats with a nine-point lead on the generic congressional ballot — their largest of the cycle — as President Trump's approval rating has slipped to a career low of 39 percent.

A Party of One

Fetterman's comments land less than three weeks after he stunned members of his own party by appearing in a taped video at the Republican Party's midterm convention, introducing GOP Sen. Dave McCormick, his Pennsylvania colleague, and pledging to work with Trump to defend Pennsylvania's steel industry. That cameo, filmed in front of a steel mill and arranged with McCormick's help, fueled months of speculation that Fetterman might eventually leave the Democratic Party altogether.

He shut that door on Saturday. "There are no Republicans with a 90% Democratic vote line," he said, arguing no equivalent home exists in the GOP for a lawmaker who supports abortion rights and LGBTQ protections. "I have no path as a Republican," he said. "I am not a Republican."

Yet Fetterman did not spare his own side either, jabbing at Democratic leadership over past shutdown standoffs and offering a mixed verdict on Senate Minority Leader Chuck Schumer. "If people are angry at Chuck Schumer, it's undeniable, he has recruited an incredibly strong class," Fetterman said, adding, "I don't sharpen blades for Chuck Schumer."

"Let's see what happens if I happen to be 51 — I don't know."

The remark was Fetterman at his most Fetterman: half joke, half warning, about the leverage he'd hold in a narrowly divided chamber where his instincts already run further from party orthodoxy than any other member of the Democratic caucus.

With his own seat not up until 2028, Fetterman's remarks amount less to a campaign promise than a preview of the balancing act Democrats could face if they flip the chamber this fall — a caucus whose majority would depend on a senator willing to cut ads for Republicans and headline their convention videos to stay unified. Pennsylvania Republicans have already signaled they see no need to court him further, telling Newsweek a party switch isn't necessary for cooperation to continue. Control of the Senate won't be settled until ballots are counted on Nov. 3, with both parties now bracing for a closer fight than either expected a year ago.
