On Fox News last night, Newt Gingrich put forth a bullish prediction, thanks to what he called "The Carville rule" -- which is that the incumbent will only get as many votes as the final poll predicts.
In other words, if there's a poll showing Romney and Obama tied at 47%, the president will end up with 47% and Romney, 53%.
"I believe the minimum result will be 53%-47% [for] Romney, over 300 electoral votes, and the Republicans will pick up the Senate. I base that on just years and years of experience.
.... You start carrying a Wisconsin, Virginia's gonna get sealed off, Florida's gonna get sealed off, North Carolina's already sealed off. As you point out, Michigan's starting to be in play, I think Pennsylvania's starting to be in play."
UPDATE: A reader passes along another conservative who's predicting over 300 electoral votes for Romney -- CNBC host, Larry Kudlow, who last night put the number at 330 electoral votes.
