From what I read in the article, AP didn’t report on it because they couldn’t corroborate her story. That’s what news outlets have to do otherwise they could get sued for slander.
The Right says Democrats have a double-standard when it comes to how the react to sexual abuse accusations in their own party, but what about Al Franken, Anthony Weiner, and John Edwards?? If anything the left will fall all over themselves to prove they are “better than the other guys” even if it means eating one of there own. On some level you have to admire the Right’s party loyalty no matter what. The GOP circle their wagons, the Left forms a circular firing squad.
