Countdown regular Dana Milbank will no longer appear on the show. After appearing on MSNBC for the past four years, the Washington Post columnist signed a deal with CNN. Last night he appeared on CNN Election Center with Campbell Brown, which airs opposite Keith Olbermann's show. Of course none of this had anything to do with MSNBC temporarily ejecting Milbank after he wrote a piece about Barack Obama that took quotes out of context and called the candidate the Democratic party's "presumptuous nominee."
