Q: How can you tell that Barack Obama is lying?
A: He's talking about health care.

Matt Welch asks, Can Obama Open His Mouth Without Lying About Health Care?

The answer is, unfortunately, self-evident. For those who don't yet recognize it,

...The president said he "didn't campaign on the public option," but it turns out he did. He said that there wasn't any "gap" between his campaign promises and the final result, but it turns out there were several, as detectable by the most cursory Google search. He said "every single criteria for reform I put forward is in this bill," but it turns out they're not.

It's seems incredible to say this, but he may be a bigger liar than the last Democratic President. Bill Clinton.
