Paul Meringoff at Powerline perfectly captures a synopsis of the true nature, relevance, and most disturbing aspect of the Obama-Ayers relationship -

In what I believe was his only stint running anything (other than the Harvard Law Review), Barack Obama wasted more than $100 million that could have been used to improve the education of disadvantaged students. And he did so in order to advance an extremist, anti-American agenda. The people of Chicago can only wish that Bill Ayers had just been somebody who lived in Obama’s neighborhood and that Jeremiah Wright was just an eccentric uncle.

As vile and disgusting as Ayers’ Weatherman Underground activities from the 70’s are, they are among the least objectionable, and most seemingly inconsequential aspects of the relationship of these two men. It isn’t so much what Ayers did before, which is horrid, but what the two men did during their time together - which is, and should be, the whole point.
