And Jonah Goldberg has the numbers to prove it.

MOST FAIR-MINDED readers will no doubt take me at my word when I say that a majority of Democrats in this country are out of their gourds.

But, on the off chance that a few cynics won’t take my word for it, I offer you data. Rasmussen Reports, the public opinion outfit, recently asked voters whether President Bush knew about the 9/11 attacks beforehand. The findings? Well, here’s how the research firm put it: “Democrats in America are evenly divided on the question of whether George W. Bush knew about the 9/11 terrorist attacks in advance. Thirty-five percent of Democrats believe he did know, 39% say he did not know and 26% are not sure.”

So, 1 in 3 Democrats believe that Bush was in on it somehow, and a majority of Democrats either believe that Bush knew about the attacks in advance or can’t quite make up their minds.

There are only three ways to respond to this finding: It’s absolutely true, in which case the paranoid style of American liberalism has reached a fevered crescendo. Or, option B, it’s not true and we can stop paying attention to these kinds of polls. Or there’s option C — it’s a little of both.
