Sen. John Fetterman (D-PA) recently told a Republican convention that he rejects socialism. That a sitting Democratic senator would go out of his way to say so is worth noticing. 

The occasion was the Republican National Committee’s first-ever midterm convention in Dallas, to which Fetterman sent a video that introduced his home-state senate colleague, Republican Sen. Dave McCormick (R-PA). After his party immediately lit him up, Fetterman was publicly promising he’s still a lifelong Democrat, still caucusing with them, and that the video only meant he and McCormick are both “Team PA.”
