The moment was the latest in a series of campaign-trail flubs for Romney, who is clinging to a narrow lead in the Michigan polls headed into Tuesday's contest.

Earlier Monday, Romney — campaigning at the Daytona 500 — was mocked for his response to a reporter's question about if he followed the sport.

“Not as closely as some of the most ardent fans, but I have some great friends who are NASCAR team owners,” Romney answered.

That comment drew derision from Democrats, who cited the comments as further example that Romney's wealth makes him out of touch with most of the voting public. During another moment while campaigning at the racetrack — where thunderstorms had delayed the sport's biggest day — Romney seemed to mock the plastic ponchos worn by a group of fans.

“I like those fancy raincoats you bought,” he said, according to The New York Times. “Really sprung for the big bucks.”

The comments came just days after the former Massachusetts governor drew criticism for his comments following a speech at Ford Field in Detroit, where he noted that his wife, Ann, owned a "couple of Cadillacs."

Still, Romney hopes his home state can deliver an important win that will soothe fears among Republicans worried that he will be unable to attract conservative support. Romney defended some of his flubs Sunday of Fox News.

“I just am who I am," Romney said.
