When David was a white house reporter he always prefaced his questions with his opinion. I think GOP candidates should do the same thing to him.
In answer to you question David, I realize that you are irretrievable biased with a left wing agenda and have no interest in hearing any other view, but for the sake of your listeners who are interested in the truth, I would point out that most of our allies think Obama is an incompetent buffoon who has made America the laughing stock of the entire world.
Laughing long and loud!! Hear, hear!!
