Romney used his campaign stops Sunday to hammer at Obama's record, particularly on the economy, saying it didn't warrant returning him to Washington.

"Throughout this campaign, using everything he can think of, President Obama has tried to convince you his last four years have been a success," Romney said at a rally in Cleveland. "So his plan for the next four years is to take all the ideas from his first term -- the borrowing, Obamacare and all the rest -- and do them all over again. He calls his plan 'forward.' I call it forewarned."
