I've just watched the interview a second time. For the record, I want to change my opinion. I want to thank Piers Morgan for the interview.
He wasn't angry. He wasn't insulting. He interrupted RP, but every time RP asked him to let him finish his thought - he obliged.
Now, let's think a little about the purpose of this interview from Piers Morgan's point of view. He wanted get the maximum exposure. That's our purpose too, right?
Now, he competed with Fox interviewing about the same time clear leaders of the race.
Well, he knew that Ron Paul supporters will be seating through the interview no matter what. So he opened his show with "Ron Paul will not win." An establishment Republican, who happened to hear that, would stay because he would want to know how to argue against RP and the media doesn't provide him with good answers. On the other hand, if he heard at the beginning how RP had a good chance to win, he would have dismissed the whole thing as RP propaganda, the same way we turn off when we hear how good Romney is. BTW, at the end of the show he let RP discuss his chances.
After that opening, he continues with diet and exercise, so that simple folks wouldn't turn off. Then he started hitting RP hard on real issues. He repeated all the main lines of attack on foreign policy, economics, and social issues. Intentionally or not, he even exaggerated the attack occasionally. (I don't think establishment would ever say that they want U.S. be the policeman of the world.) He interrupted RP when he would go in educational mode and forced him to be as sharp as knife in his answers. Ron Paul by nature is not antagonistic and doesn't like to be in your face but he can do it when he is against the wall, and boy he certainly did it in this interview.
Ron Paul came out of this interview looking great, humble, looking personal, and looking presidential for his supporters, for the establishment, and for non-political people.Piers Morgan didn't come out looking good, so what?
Not on behalf of Ron Paul supporters, but from me personally, Piers Morgan - thank you.
