WASHINGTON: On the eve of their next fateful date with Democratic voters, Senator Barack Obama has said that he is confident of winning the party nomination but the race will not over until Senator Hillary Clinton quits.

"I don't think the race is over until Senator Clinton decides that she's getting out or until all the primaries and caucuses have taken place," Obama said during NBC's 'Meet The Press' .

"... We are going to keep on going, and we feel confident that ultimately I'm going to be the Democratic nominee," the Illinois democrat said.

Obama said: "...I think the super delegates, by rule, can make their own decision. I think the super delegates are going to take a look not at momentary snapshot polls, but they're going to take a look at who's run the campaign that can bring about change in American and can actually govern after the election."

He said that the number of new people that we've brought in, the organisations that we've set up in all 50 states, the energy that our campaign has displayed indicates to me and should indicate to the super delegates that the American people are ready to move in a new direction, and that's what we're offering.

"I'm confident, if I am the nominee, that I'll offer Democrats the best chance of winning in November," Obama added.

As per a latest delegate count, Obama has 1492 and Senator Clinton 1338. In the super-delegates category Clinton has 274 as opposed to Obama's 253 with 268 still uncommitted.
