Liberal pundit Ed Schultz called Republican electoral gains “huge.” And no race was bigger, in his opinion, than Gov. Scott Walker’s victory in Wisconsin.

“What hasn’t this guy done against the progressive movement? And he’s been victorious at almost all of it,” Schultz said on MSNBC.

Schultz, an outspoken critic of Walker, rallied liberals in a failed recall election against the governor in 2012. He noted that Walker has now won three statewide races in a span of four years, a feat he called “unprecedented.”
