He was OK while at ABC that he asked some questions that the other obama ass-lickers in the press wouldn’t ask. When you join CNN, it’s in the contract to switch sides.
No doubt he feels much freer to practice his progressive religion at cnn... but I never liked him at abc. You are correct that occasionally he did ask questions that other journolistas would never ask. Being the best turd in a punchbowl does not make you an orange slice. ;-)
