CEDAR RAPIDS, Iowa - Landing his campaign plane just yards away from a hangar full of supporters in the Hawkeye State, a revved up Mitt Romney predicted a win for himself on Election Day, now just 12 days away.

"The Obama campaign is slipping because it can't find an agenda to help the American families, but our campaign is growing into a movement across this country that says we're going to get America back, we're going to get America strong, we're going to provide for our families," said Romney. "And I'm optimistic. I'm optimistic not just about winning. We are going to win by the way. And we're going to do that."

Recent polls have Romney and Obama neck-and-neck. Romney eked out a slight edge nationally in the latest ABC News/Washington Poll poll, 49 to 48 percent among likely voters.

"I'm not just optimistic about winning," Romney said. "I'm more optimistic about the future of America."

It was the second time today that Romney predicted a win for his ticket, with his first prediction coming earlier in the day in Reno, Nev.

"He doesn't have a plan to get jobs for Americans," Romney said of President Obama during a rally in Reno. "I do, and that's why I'm gonna win."
