The seemingly lone conservative at MSNBC is out of the anchor chair, at least for now. The Associated Press reports that Tucker Carlson’s “Tucker”  show on that cable news network has been cancelled. He’ll reportedly be replaced by NBC firebrand David Gregory. Gregory’s show, Race for the White House, begins one week from tonight at 6 p.m.

MSNBC says this and other changes the network is making are in response to the growing demand for more political news. (Gosh, it seems like that is all they do now besides all those prison reality shows and constant repeats of To Catch a Predator.) Other changes announced are that NBC reporter Andrea Mitchell will now permanently anchor one hour a day on MSNBC Monday through Friday and that Countdown With Keith Olbermann will rerun every night at 10 p.m.

Tucker Carlson, who is 39, has been at MSNBC for nearly three years. He’ll reportedly stay at the network as a campaign reporter.

Before his stint at MSNBC, Carlson worked at CNN as the right wing half of the political debate show Crossfire. He also hosted a weekly public affairs program on PBS. Carlson also writes for Esquire, The Weekly Standard, The New Republic and the New York Times Magazine.

Carlson has also appeared on ABC’s Dancing With the Stars.

He was voted off after one episode.
