As the recent outpouring of raw, naked outrage on the NRCC web site makes both manifest and plain: insofar as the voting conservative base is concerned, he demonstrably has not done so.
Responsibility for the adamant rejection of John McCain by the conservative voting bloc, therefore, rests ultimately with the unsatisfactory candidate, and he alone.
It does no good whatsoever to hop up and down like so many amphetamined spider monkeys, agitatedly shrilling "OBAMA! OBAMA! OBAMAOBAMAOBAMA!!!," as Barack Obama is not running as the Republican candidate for the presidency this year; McCain is. He either closes the deal himself, based on his ability to persuade conservatives what he himself has to offer them (if anything)... or: he does not.
McCain has made me very angry in the past, especially on immigration (I can't for the life of me figure out why he's so deluded on this topic), but to his credit, he voted against this POS Farm Bill. He also vocally opposed ethanol subsidies, while campaigning in Iowa. That takes guts.
McCain's fiscal conservatism is beginning to win me over, I must say.
But I'm still very concerned about his stances on immigration and foreign policy.
