CNN’S LOSS IS CNN’S GAIN…. Trust me, CNN, Fox News has done you an enormous favor.

The Fox News Channel brought in a big name from a rival Thursday when it announced that it had signed Glenn Beck, the host of a widely viewed talk show on Headline News, a sister network of CNN.

Mr. Beck, who has frequently raised hackles in liberal circles with his acerbic conservative commentary, will host a new talk hour on Fox News from 5 to 6 p.m. weeknights. The show will not start until the spring, and a CNN press officer would not say when Mr. Beck would conclude his shows there. His contract ends in February. […]

Roger Ailes, the chairman of Fox News, said in a statement, “Glenn’s thought-provoking commentary will complement an already stellar lineup of stars at Fox News.”

Yes, “thought-provoking,” such as, “I think CNN is humiliating itself by paying this nut.”

Media Matters and ThinkProgress have some of Beck’s “greatest hits,” but some of my personal favorites include the time Beck called Hillary Clinton and John Edwards “communists,” the time he explained why he agrees with the John Birch Society, the time he said he agreed with al Qaeda about the moral degradation of America, and of course the time he confronted Rep. Keith Ellison (D-Minn.), the first Muslim to serve in Congress, asking, “Sir, prove to me that you are not working with our enemies.”

That CNN actually put this man on the air was an embarrassment to the network. He’ll fit in nicely at Fox News.
