ABC News' Teddy Davis and Rick Klein Report: Count Al Gore among those who don't think the Democratic primary race will go all the way to the convention.Appearing Tuesday on National Public Radio's "Fresh Air," the former vice president held out the possibility of making an endorsement in the race -- but predicted that superdelegates will tip the race to either Sen. Barack Obama, D-Ill., or Sen. Hillary Rodham Clinton, D-NY, before the Democratic National Convention in Denver this August."Even though it has gone on much longer than is normal in the age of primaries and caucuses, nevertheless I think the odds are overwhelming that it will tip rather decisively in one way or the other before the convention even meets," Gore said. He said he does not anticipate having to help broker a solution to the Democrats' stand-off."I'm not anxious to be playing the role of party elder," he said. "I just turned 60 -- which is the new 59. So I'm just a voter and recovering politician.""My purpose is not endorsing a candidate is not elaborate. I'm simply watching and listening to the campaign," he added. "As a delegate to the convention I will cast my vote at the proper time. I haven’t ruled out making an endorsement prior to that time, but I haven’t been moved to do so. . . . I have respect for both candidates, and they both have strengths, and I’m simply listening and watching like a lot of people."Gore said the Democratic Party's system of awarding votes to superdelegates "probably . . . should be examined," and said he's confident that the disputed delegations from Florida and Michigan will be seated at the convention, though he didn't say how.On the possibility of a split Democratic Party this Fall, he said: "I would not underestimate the healing power" of the desire to win.
