The lie is being told often enough that many people actually believe it.

Writing in the Weeky Standard Blog , Stephen Hayes points to Obama's interview in WaPo where he repeats, for the umpteenth time, the lie that "all economists" believed some kind of stimulus package was necessary to save us from a "Great Depression:

Barack Obama, discussing deficits and the stimulus, in an interview with the Washington Post's Fred Hiatt: "The reason that it hasn't been at the forefront of my agenda is because I walked in when we were about to slip into the Great Depression -- or the next Great Depression. And so I had to start off, coming out of the box, with a recovery package that, whatever arguments may be made by the critics at this point, there was no economist out there who thought we didn't need to do."

Right. Except for these 200, a list that included several Nobel laureates. What makes this fib by our president especially galling is that the content of the ad taken out by the Cato Institute that listed these economists. It began by correcting Obama's claim, on January 9, that "there is no disagreement that we need action by our government, a recovery plan that will help jumpstart the economy."

The economists wrote: "With all due respect, Mr. President, that is not true."

It's still not true, however many times he says it.
