The ad also misquotes Obama. It says he defended himself against the “most liberal” rating by saying “they’re not telling the truth” and “folks are lying.” Actually, Obama said McCain and Palin weren’t truthful about the “Bridge to Nowhere,” and he was correct. And his “folks are lying” remark referred to anti-abortion groups that accuse him of favoring “infanticide” because of votes he cast in the Illinois state Senate.
After twisting Obama’s words, the ad accuses him of being “not presidential.”
And McHack is?
Well, maybe. Given the record of the Current Federal Administrator, I guess lying is the presidential thing to do.
