Donald Trump on "Hannity" Thursday night:
He's been a horrible president. I always said the worst president was Jimmy Carter. Guess what? Jimmy Carter goes to second place. Barack Obama has been the worst president -- ever. The history of America -- Barack Obama is No. 1."

Donald Trump in an exchange with CNN's Wolf Blitzer; September 2007:
Trump: A Democratic candidate -- whoever wins (the primary) -- is going to have a huge advantage because of Bush. People don't like him. People think he's been a horrible president, possibly the worst in the history of this country.
Blitzer: You believe that.
Trump: Oh, he's been a terrible president.
Blitzer: You think he's the worst in the history of the United States.
Trump: I don't think you can get much worse. Why? I mean, who's worse? Give me a couple of names. Who could be worse?
Blitzer: Because in the last interview we did in March, you said he was the worst.
Trump: Well, at least I'm consistent.
