Obama campaigned Monday in Florida, a populous state in the southeastern U.S. that would give either candidate a significant push toward the White House. On Monday evening, he and Clinton appeared together in Orlando. The pair urged supporters to vote and cautioned against overconfidence. Most public opinion surveys show Obama leading Mc Cain by about five percentage points. Obama criticized Mc Cain's campaign tactics, accusing him of resorting to personal character attacks.
