Marion, Iowa (CNN) - Projecting a newfound confidence on the eve of the Iowa caucuses, Mitt Romney spoke enthusiastically Monday about his chances in the upcoming contest.
The GOP candidate encouraged an audience of roughly 400 Marion voters to caucus for him Tuesday, telling them: "we're gonna win this thing."

"I need you tomorrow night. I need every single vote in this room and I need you to get another couple of other votes from your neighborhood and get them to caucus," he said. "I need a great showing here in Cedar Rapids. We're gonna win this thing with all of our passion and strength and do everything we can to get this campaign on the right track to go across the nation and to pick up other states and to get the ballots I need and the votes I need to become our nominee."
A campaign aide downplayed the remarks, and said Romney had been referring to winning the nomination, a frequent line in his speeches.
Romney has long been cautious about his chances in Iowa, remarking about the fluidity of the polls and saying he would be happy to merely do well.
On Sunday Romney told members of the media: "I don't know that you can look at a poll and project from that what's going to happen on caucus night."
In his Monday speech, Romney unveiled a harsh new line of attack on President Obama. The GOP candidate said the president and his allies were trying to turn America into an "entitlement society."
"They'll poison the very spirit of America and keep us from being one nation under God," he said. "I've watched a president who's become the great divider, the great complainer, the great excuse-giver, the great blamer. I want to have an America that comes together."
