The reason I don't buy that is because romney will not have a mandate to govern from the left. If you look at the exit polls, he has won conservative, tea party support and "anybody but obama support. He knows the country wants an alternative to obama and if he's going to beat him, he has to run to the right. The people can keep him in check for four years and primary him if necessary. There's no keeping obama in check. Romney will buy us time.
