It's a constant of nature, like Planck's

Kevin Drum is astonished that 52% of Republicans think ACORN somehow stole the 2008 election for Obama:

There aren't words for this. Something like 40 million Republicans are now convinced that ACORN (!) somehow managed to steal an election that McCain lost by seven percentage points. Another 20 million think they might have stolen it but aren't sure. The Fox/Limbaugh/Palin axis, which probably directly reaches maybe 10 million people on a regular basis, has nonetheless convinced six times that number to buy into a conspiracy theory that makes the Area 51 crowd look sane by comparison.

Drum's chart however makes the answer clear: 26% of all persons polled buy the ACORN theory. And that's well within the margin of error of the 27% Crazification Factor.

John: You realize this leads to there being over 30 million crazy people in the US?

Tyrone: Does that seem wrong?

John: ... a bit low, actually.
