<<Ayers is NOT just some guy in the neighborhood.
<<He very possibly is why Obama is where he is right now.>>
Nope. Obama is why Obama is where he is right now.
Nobody has any magic wand, least of all Ayers. Obama's a smart guy with a huge ambition. If not Ayers, someone else would have given him a leg up. Obama's magic. Lots of people would fight for a piece of it.
I'll pass on the credibility issue. First of all because it's a fake issue. No one really expects the kind of credibility from a politician such that he won't try to spin, to minimize unfavourable associations and that's all that Obama's been guilty of. Ayers is news for only one reason, and it has nothing to do with credibility: it's for the smear value, the muck value.
Ayers' name is invoked at McSame/Palin rallies for only one purpose, as is evident from the response; to whip up violent hatred against Obama. Be honest - - you hear those boos, those shouts, "Kill him!" "Traitor!" etc. These aren't folks upset at a lack of candor. When the issue is lack of candor, the audience reaction is derisive laughter mixed with boos. Not "kill him" and not "traitor." These are folks who have bought into the campaign's picture of Obama as terrorist, as Muslim, as enemy of America. First Ayers' picture is painted, then it's associated with Obama. Obama is Ayers, Ayers is the enemy.
