Mitt Romney admits he's responsible for not having already secured the Republican nomination for the presidency, but he's not willing "to light my hair on fire" to do so. After harming his campaign in the week before Tuesday's crucial Michigan primary with tone-deaf comments about his wife's Cadillacs and his friends' NASCAR teams, the former Massachusetts governor plans to change the tone of his campaign before Super Tuesday. "I'm trying to do better and work harder and make sure that we get our message across," he said in Michigan. Polls on Tuesday have shown Romney and competitor Rick Santorum neck and neck in Michigan's primary.
