Well I don't know about a landslide but that might happen. Republicans continue to follow the extreme of their party against the main stream of thought. They are too clouded with frothy fervor for Palin and Bachmann to realize those girls will not win the hearts and minds of the rest of us including many independents.
R. Paul might trigger that unsettled feeling many of us have with how things are gong sending people to the voting booth. Mitt Romney could hold his own in a debate imho. I doubt either will win the nomination, so Obama it is, for four more years.
But look on the bright side Republicans, if the country follows form there will be a restlessness again in 2016. Then you can have that perky eared doe eyed kid Ryan all primed and ready.
