I saw the interview, and I’m not sure McCain went in planning on calling for repeal of Obamacare, but Greta boxed him into it. She asked him 4 or 5 questions about it, and after he answered them she specifically asked if that means he supports repeal. He looked like he had an aha moment and said yes he does.
Those were my impressions.
This is something that should be HEADLINED on the Drudge Report.
