In the roughly one-minute video introducing McCormick on stage, Fetterman made clear that he is still a Democrat. But took aim at the rise of “socialism” in his own party – a notable and public rebuke to the Democrats’ left flank.

“Yes, I’m a Democrat. Why am I here talking to you today? Because well, I’m a common sense Democrat. I’m always going to stand with America. I’m always going to reject the extremes and socialism and that anti-American way of life,” Fetterman said in the pre-recorded video.
