Pennsylvania Democratic Sen. John Fetterman has finally responded to growing rumors in DC and online that he plans to switch his party affiliation to the GOP.

That’s “not going to happen,” he told Semafor on Monday.

“That’s amateur hour s**t,” he said. “If they think, ‘oh, it’s going to be like a Manchin or a Sinema play,’ that’s just not true, and that’s not going to happen.”

He was referencing now former Sens. Kyrsten Sinema (Ariz.) and Joe Manchin (W.V.), who famously left the Democratic Party to become Independents — though they still caucused with Dems.

“It’s not gonna happen,” he added. “And even if I wanted to do that, that is a rocket sled to Palookaville to try to switch. I would make a pretty bad Republican.”

The Pennsylvania Democratic senator has sparked significant interest with his recent visit to Mar-a-Lago to meet President Donald Trump, his collaboration with Republicans on the Laken Riley Act, and his vocal support for the Israeli government.

He is actively working to reshape his party’s approach to Trump, encouraging Democrats to remain calm about the president’s controversial actions and to remain open to confirming his nominees.
