In an interview before the rally, Romney said he’s not concerned about polls that are trending against him. When asked if he could lose Michigan, Romney replied “that won’t happen.”

“You have seen just how mercurial the sentiments of voters are until they get to know the candidate,” Romney told the Press and mlive.com. “It’s always been a two person race. First, it was me against Donald Trump, then it was me against Michele Bachmann, me against Newt Gingrich and now it’s me against Rick Santorum.”
