The matter of the missing visceral repulsion.

David Limbaugh's does the best of anyone I've seen of capturing the problem with Mr. Obama's associations with William Ayers – no repulsion:

No matter how much apologists insist his longtime association with the Rev. Wright is irrelevant, a good percentage of Americans will not be fooled. No matter how glibly Fox News' Alan Colmes speciously claims it's unfair to impute to Obama the views of former terrorist William Ayers, it's damning enough that Ayers and everything he stands for don't viscerally repulse Obama. How can Americans prudently entrust the Oval Office to a man who would have anything to do with a self-professed, unrepentant Pentagon bomber, much less allow this anarchist to throw a state Senate fundraiser for him?

The same point is applicable to the "Rev." al-abu-bin-Wright. Obama's edging away from him is measurable only in centimeters in the single-digit range.

Obama, it would seem, has the ability to eat dinner with a dead skunk in his lap and not notice the smell.
