Romney running mate Paul Ryan is in Wisconsin today. In Eau Claire, he talked of an American renaissance: "Our commitment is really clear. We're saying here are the solutions; here are the principles we're going to use; here's our proven bipartisan track record of actually delivering results and getting things done; here's what we're going to do. And I've got to tell you, 2013 could be a renaissance in America, in the world and in America. 2013 can be the year we get our economy growing, we start creating 12 million new jobs, we put these pro-growth policies in place and we reaffirm the American idea by electing Mitt Romney the next President of the United States."
