ABC News' George Stephanopoulos Reports: In an exclusive interview with former President Jimmy Carter set to air on Sunday's "This Week with George Stephanopoulos", Carter lavished praise on "(his) favorite Democrat) former Vice President Al Gore.Carter told ABC News, "If Al should decide to run -- which I'm afraid he won't -- I would support Al Gore."The former Democratic President asserted Gore could accomplish much more in the White House than he ever could as a private citizen, saying to Stephanopoulos, "His burning issue now is global warming and preventing it. He can do infinitely more to accomplish that goal as in the incumbent in the White House, than he can making even movies that get -- you know, that get Oscars.""An Inconvenient Truth", a documentary based on a global warming lecture Gore has delivered around the world, is nominated for an Academy Award and the former Vice President will walk the red carpet at the Oscars this Sunday.Despite public pressure from Carter and others, the former President does not believe Gore will make a second bid for the White House saying, "I don't think he will. I've put so much pressure on Al to run that he's almost gotten aggravated with me."Carter told Stephanopoulos that he had not called Gore "lately" adding, "He almost told me, the last time I talked, 'Don't call me anymore.'"Carter joked that Gore had offered to support him in 2008 and referred to Gore as "my favorite" in the interview, concluding, "I really have not expressed any public approval or endorsement or preference for any of the Democratic candidates except (Gore)."Tune into 'This Week' on Sunday, February 25, to watch George's full interview with former President Carter.
