To be fair, I'm sure if the pollsters would have told the Republicans polled that Acorn no longer existed, at most 48% of them would have maintained that Acorn stole the election.
I had a spirited discussion with a Republican a couple days after the election who said that "obviously" the election had been stolen as there had been widespread vote fraud in Ohio. I said "I don't think so, but for arguments sake, let's accept that and throw out Ohio's electoral votes. Obama still won." She thought a bit and added "And Florida. There was vote fraud in Florida."
I said "OK, let's toss out Florida too. He still won."
Without batting an eye she said "How many states would Romney need? There was fraud all over."
I think a lot of this is attributable to the echo chamber that is Fox 'News'. They've been pushing voter fraud as a legitimate issue for four years now, and they were skeptical of the results as they came in on election night. Plus, most if not all of their pundits had predicted a Romney victory. Given that so many of their viewers rely on them as their sole source of information, it isn't surprising that their opinions are skewed.
