Lou Dobbs A "Publicity Nightmare" For CNN: AP

AP -- He's become a publicity nightmare for CNN, embarrassed his boss and hosted a show that seemed to contradict the network's "no bias" brand. And on top of all that, his ratings are slipping.

How does Lou Dobbs keep his job?

CNN insists it is standing behind Dobbs, despite calls for his head from critics of his reporting on "birthers" - those who believe President Barack Obama wasn't born in the United States despite convincing evidence to the contrary. The "birthers" believe Obama was born in Kenya, and thus not eligible to be president.

Dobbs' work has been so unpopular that even Ann Coulter has criticized him.
