(CNSNews.com) - "I spoke with Elizabeth (Warren) today," Sen. Bernie Sanders told MSNBC's Rachel Maddow Wednesday night. "It's a private conversation, but I think Senator Warren has worked really hard over the last year.
"She has run in many ways an excellent campaign, bringing out a whole lot of ideas which I think have expanded political consciousness in this country. She's now assessing where she wants to go, and she deserves the time and the space to make that decision."
Asked if he would consider asking Warren to be his running mate, Sanders responded, "It's too early to talk about that. Certainly I have a lot of respect for Senator Warren and would love to sit down and talk to her about what kind of role she can play in our administration."
Looking ahead at what now appears to be a two-man race for the Democrat presidential nomination, Sanders said he wants both sides to avoid "personal attacks."
“Look, Joe Biden is a very strong opponent. He will have all of the corporate world behind him, the political world behind him. This is what we're going to do, Rachel, and I've got to tell you, I hope very much this doesn't come into some kind of ugly personal attacks, because I like Joe Biden. He's a very decent guy, but what is important for us is to contrast our record, our vision for the future with Joe's. And that's what we're going to do.”
Sanders aims to 'transform this country’
Sanders said he's "feeling good" about his prospects for getting the nomination:
"I think we've got a real path toward victory. I think if you and I chatted a year ago when we began the campaign and we said in an unprecedented way, taking on all of corporate America, wall Street, the insurance companies, the drug companies, the fossil fuel industry -- taking on the entire political establishment, that today, a year later, we would be within a few -- I don't know when they finish counting up California, we may actually have a few more delegates than Biden does.
"I'm not quite sure that many people would have thought that we would be where we are today. So I'm pretty proud of the unprecedented kind of coalition that we're putting together and the movement that we're developing."
Sanders told Maddow, "We're trying to transform this country, not win an election. Not just beat Trump. We're trying to break up large banks. We're trying to substantially lower the cost of prescription drugs. We're trying to do what every other major country on Earth does, provide health care to all people as a human right. We have introduced most sweeping and comprehensive climate change proposal ever introduced by a federal candidate…”
Sanders said he's proud of all he's accomplished despite taking on the "corporate establishment," including the "corporate media."
"I will be the first person to tell you it is hard. Okay? I'm not running a conventional campaign. We call our movement ‘us,’ not ‘me.’ I'm not saying vote for Bernie Sanders, we're going to solve the problems.
“We are in this together because the only way real change...whether it's the civil rights movement, the labor movement, the women's movement, the gay rights movement, the environmental movement, how does change happen? When millions of people stand up and demand it.
"That is what this campaign is all about. It's a different type of campaign, and we're doing quite well. Right now as of today, we may or may not be appointed a delegate or two ahead of Biden or a delegate or two behind him, I think that's pretty good, and I think that given the agenda that we are bringing forth, that we have a shot to win the democratic nomination and a shot to defeat Donald Trump. I think that's pretty good."
And if Biden ends up with more delegates than Sanders does, heading into the Democrat convention?
"Of course I'd drop out, he will win," Sanders said. "We'll run through -- I suspect we will run through the process letting people have a right to vote, but if Biden walks into the convention or at the end of the process has more votes than me, he's the winner.
Sanders said he's confident that every Democrat who ran for the presidential nomination will support the winner. "I will support Biden. Biden will support me."
But Sanders rejected the idea of a Biden-Sanders or Sanders-Biden "unity ticket."
"You mean two old white guys on the ticket? Well, probably not. I think the American people don't want -- one old white guy is probably too many for some."
