According to the latest PPP poll, Republicans believe, 52 to 27, that ACORN stole the election for Obama. They really believe that ACORN altered the outcome of the election to the tune of 10 million votes. The wingnuts really, sincerely believe that Obama is an illegitimate president, independent of the whole birther thing.
So the lunacy of the teabagger movement becomes easier to understand.
But they're still, um, insane.
