Let's talk about the weather

AP's got a good fact check up breaking down what was said last night and what's true re: the Weather Underground:

Facts were loose in both Democratic presidential campaigns Thursday as Clinton sought advantage from her rival's association with William Ayers, a college professor who was once part of the violent Weather Underground group.

The dustup arose in their debate the night before and enveloped both candidates.

Obama struck back by calling attention to Bill Clinton's decision to pardon one former Weather Underground member and commute the sentence of another, clearing two women who — unlike Ayers — had been convicted of crimes from that era.

It's interesting. You know why? Because I didn't know much about the Weather Underground. Now I do. You know who else probably didn't know much about the Weather Underground? Most of the people watching last night's debate hoping to get information about stuff that really matters.
