Great For The Goose, Bad For The Gander

When Factcheck.org criticizes the accuracy of Sen. John McCain's ads, which is has done on numerous occasions, it's.. like a annoying fly that keeps buzzing around the candidate's face. (McCain on August 1:  "I don't respond to websites that I have no idea what they're talking about.)

But when it tweaks Barack Obama for exaggerating a point in one of his ads, it's apparently an eminently credible non-partisan fact-checking organization... so suddenly credible, in fact, that McCain's campaign is comfortable borrowing their authority to blast Obama.
