ABC is going to regret asking Christiane Amanpour to take that seat. She is just about as likable as a viper and dumb as a box of rocks. Worse, she has been exposed as a tireless shill for anything anti-American, so she is a "must get" for the Obama crew. But the business of TV is ratings and she is not ready for Prime Time.
ABC lost the opportunity for someone who could be the next Tim Russert for ABC News and passed the chance because the Obama people hate Tapper because it plays it straight down the middle and they can't afford anything like that.
