His personality. His lack of humor. His liberal weenie campaign of 2006. His lying about his liberal weenie campaign of 06. His pro union stances. His big government stances. His very mediocre conservative record outside of social issues. His real good chance of totally off putting the electorate in the general. His idiotic thinking that social issues are the key to 2012. His votes to increase welfare spending. His nanny state vote forcing businesses to pay benefits to those they lay off. His Pet Animal Welfare Statute bill. His pretending to stay above the fray while running awful negative ads himself. His claiming that he has won "four states" when they were all teeny tiny caucuses. His open mouth insert foot on sex for procreation. His sweater vest.
Other than that, not much.
