Coulter banned on NBC

According to the Drudge Report, controversial conservative author Ann Coulter is banned from appearing on NBC:

"We are just not interested in anyone so highly critical of President-elect Obama, right now. It's such a downer. It's just not the time, and it's not what our audience wants, either."

That's probably true. Whoever watches NBC probably isn't interested in Coulter's criticism of liberals. But a complete ban based on the reasoning that she's critical of our president-elect? NBC ought to be ashamed! Why didn't they ban those who were highly critical of President Bush? The elite media double standard at its best.
