“I’d drive his bus if he asked me to,” Ryan, who ran alongside Romney for vice president in 2012, said in an interview with Bloomberg Television.

Ryan said that he believed that a lot of voters now had “buyer’s remorse” about giving Obama a second term.

“A lot of the things [Romney] said in the campaign, projections he made … were true,” he said.

The House GOP heavyweight sidestepped questions about whether he plans to mount his own presidential bid in 2016, saying, “I honestly don’t know what I’m going to do on that.”
