Back in October, I wrote a Slate piece on “Election Truthers,” asking “What if President Obama wins re-election and Republicans don’t believe it? The question isn’t far-fetched. For several weeks, we have seen Republicans challenge the veracity of a number of election-related facts, and the outcome of the presidential election may be no different.”

From a PPP poll released today: “49% of GOP voters nationally say they think that ACORN stole the election for President Obama. We found that 52% of Republicans thought that ACORN stole the 2008 election for Obama, so this is a modest decline, but perhaps smaller than might have been expected given that ACORN doesn’t exist anymore.”

Caveat: “One reason that such a high percentage of Republicans are holding what could be seen as extreme views is that their numbers are declining. Our final poll before the election, which hit the final outcome almost on the head, found 39% of voters identifying themselves as Democrats and 37% as Republicans. Since the election we’ve seen a 5 point increase in Democratic identification to 44%, and a 5 point decrease in Republican identification to 32%.”

Also interesting is polling comparing public support for Simpson/Bowles with public support for a mythical Panetta/Burns plan.  (Wondering if Burns is Montgomery Burns.)
