The McCain campaign is now running an ad saying that Obama is not truthful about taxes, and that he has voted 94 times to raise taxes. For the last time, McCain, Palin, their surrogates and the GOP are intentional liars.
This assertion has been fact-checked by several organizations, and it has turned out to be false every time. Repeating it on the stump, in debates, ads and on talk shows does not make it true. It just makes the McCain campaign harder and harder to tolerate with every day that goes by.
