Bernie Sanders in the Democratic race "until the last vote is cast"

Sanders vows to stay in race until convention... 02:31

The Democratic race is just about over. Bernie Sanders won Indiana Tuesday night, but essentially split the delegates with Hillary Clinton, who now has 92 percent of the delegates she needs for the nomination.

But Sanders told "CBS Evening News" anchor Scott Pelley he's not going anywhere -- he's staying in the race until the very end.

SCOTT PELLEY: Senator Sanders, let me begin by acknowledging that I was dead wrong. After our interview I suggested that New Hampshire would be your last victory party, and you've had 17 victory parties since then. But if I was wrong then, isn't the party over now?

BERNIE SANDERS: Well, I really don't think so. I think we have a path toward victory. I admit that it is a narrow path. But we think everybody in this country -- people in California, in Kentucky, in West Virginia -- have a right to determine who they wanna see as President of the United States and what kind of agenda they want the Democratic Party to have. So we're gonna fight, Scott, for the very last vote that we can get.

PELLEY: Is defeating Trump the Democrats' highest priority?

SANDERS: Absolutely. I think that Mr. Trump would be a disaster for this country.

PELLEY: But are you now standing in the way of defeating Donald Trump?

SANDERS: No, on the contrary. Look, my candidacy, what we call the political revolution, has energized millions and millions of people -- working people, young people. And the way Democrats win elections is when the voter turnout is high, when people are excited. And that's what we are doing.

PELLEY: To those who say that Secretary Clinton's delegate lead is insurmountable, you say what?

SANDERS: I say that we have a narrow path. It's a tough hill to climb. I acknowledge that. But I think we have a shot. A lot of the superdelegates, I hope that they will listen to the people in their state and say, "Hey, we delivered for Bernie with landslide numbers. You, as superdelegates, have gotta listen to us."

PELLEY: But Secretary Clinton has won, by far, the largest number of votes. How do you convince the superdelegates that they should go your way?

SANDERS: I think we make the case that ... if you look at virtually all of the polling nationally and in battleground states, Bernie Sanders does much better against Donald Trump than does Hillary Clinton.

PELLEY: Do we have your word, in this interview, that you're not gonna drop out before the Democratic Convention?

SANDERS: Absolutely. We have made that commitment. I'm gonna be in it until the last vote is cast.
