Democrats once hailed Sen. John Fetterman (D-Pa.) as the party’s poster child: A plain-spoken, hoodie-wearing populist who appealed not just to those in his party but to independents and even some Republicans.

Lately, though, some Democrats say he’s appealing to Republicans and turning his back on his party with remarks defending Trump and attacking his party over their criticisms of the White House.

As the Pennsylvania senator increasingly clashes with progressives and breaks with his fellow Democrats on a string of issues, some in the party are comparing him to former Sen. Joe Manchin (W.Va.), another Democrat who some in the party say boosted Republicans while hurting his side.
