John McCain does not have half the political skills of the Clinton tag team. Hillary raised more money then McCain, built a bigger organization then McCain, got more votes then McCain. The Democrat who finished second out-classed McCain by any and every measure. McCain besides being weaker then Hillary in every metric has 2 huge additional disadvantages. He's a Republican and he has GWB hung around his neck like a 100lb albatross.
Obama has already beat the strongest candidate this election cycle.
