GOP REACTION: Senator Mike Lee says, "Democrats are going to lose...because they haven't offered anything that's new or appealing to the American people." PREDICTIONS MARKET: Foolish Republicans killed off Intrade.com, the useful betting site that predicted elections and other future events better than polls and pundits did. Now there's another prediction market, England's Betfair, plus polls and predictors like Nate Silver's FiveThirtyEight blog. Who will be most accurate this time? ELECTION PANEL: Fox Contributor Deroy Murdock, Austin Petersen of the Libertarian Republic, and Katherine Mangu-Ward of Reason offer their perspectives. LIBERTARIAN CANDIDATES: Libertarians probably won't win any seats. So why run? Libertarian senate candidate in North Carolina Sean Haugh says, "voters are ready to take back their government by voting for independent and third party candidates."
