Too bad this isn't 2004, huh? Otherwise, Obama would be looking pretty good right now. Alas, economic/social conditions are not favorable towards re-election based solely upon personal likeability ratings.
2004 was about sandwiches, not barbeque, and John Kerry's preference for swiss cheese seemed to have made him a poor dinner guest. (Never mind Bush's choking on a pretzel the year before! That seemed to have been forgotten. Besides, Condi was manning the grill in Crawford and wouldn't let Bush anywhere near it after that segueway incident, so Bush was safe.)
Too bad Hermann Cain isn't still in the running. He'd make a fine dinner guest, imho.
