Rita Cosby #1 In 25-54 Demo Tuesday

How often can MSNBC claim a primetime win? Rita Cosby beat Sean Hannity, Alan Colmes and Ryan Seacrest on Tuesday night — in the 25-54 demographic, anyway.

Between 9 and 10 p.m., she averaged 327,000 viewers in the demo. Hannity & Colmes had 299,000 and Larry King Live had 235,000. Cosby hosted segments on an Iowa manhunt, the death of WWE star Eddie Guerrero, and the cell phone bandit.

Among total viewers, H&C dominated, with 1,833,000 P2+. CNN was second, with 818,000, but MSNBC wasn’t too far behind, with 681,000. Apparently Seacrest and Nicole Richie don’t draw in many viewers.
