On Tuesday, in his now infamous “green backdrop” speech, McCain basically called Obama a liar:

You will hear from my opponent’s campaign in every speech, every interview, every press release that I’m running for President Bush’s third term. You will hear every policy of the President described as the Bush-McCain policy. Why does Senator Obama believe it’s so important to repeat that idea over and over again? Because he knows it’s very difficult to get Americans to believe something they know is false. So he tries to drum it into your minds by constantly repeating it rather than debate honestly the very different directions he and I would take the country.

Once again, McCain’s ignorance of the Internet is his undoing. To wit, John McCain on June 15, 2005, on Meet the Press:

MR. RUSSERT: And what people point to — and this is an article in your hometown paper, the Arizona Republic, “At Odds With Bush. John McCain repeatedly has taken maverick positions that have put him at odds with President Bush’s administration” … The fact is you are different than George Bush.

SEN. McCAIN: No. No. I — the fact is that I’m different but the fact is that I have agreed with President Bush far more than I have disagreed. And on the transcendent issues, the most important issues of our day, I’ve been totally in agreement and support of President Bush. So have we had some disagreements on some issues, the bulk — particularly domestic issues? Yes. But I will argue my conservative record voting with anyone’s, and I will also submit that my support for President Bush has been active and very impassioned on issues that are important to the American people.

So, according to McCain, on the important issues, he is indistinguishable from (“totally in agreement and support”) Bush.

Of course, not everyone thinks so … VP Dick Cheney took time out from his busy schedule to criticize McCain’s plan to cut the gas tax.

If you still don’t believe that McCain will lie to get elected, watch McCain himself admit it in this video (forward to 6:20).
