Saunders has no doubt that Sanders will continue to win primaries, but says that in the end, "it will be extremely difficult for him to get the nomination."
"Still, I'm proud of him because the one thing he's done is brought economic fairness to the forefront of the Democratic party. He's introduced the subject into the conversation and people are talking about it. I mean, did you hear Hillary's victory speech on Super Tuesday? She talked about economic fairness, and about having to stop Wall Street.
"Now, I didn't believe a minute of it, but she sounded more like William Jennings Bryan than William Jefferson Clinton, and I think that's directly attributable to Sanders being in the race," he says.
Understandably, in the midst of primary season, Saunders speaks a lot about personalities and strategy. Those he likes and those he dislikes. For a moment though, he reflects on his own experiences and the lessons he learned while on the presidential campaign trail with Edwards.
"The first race, in 2004, was fun," Saunders says. "I was just coming off the successful Warner campaign in 2001 a contest in which we got the majority of the rural vote in Virginia, the first time any statewide candidate had done so in 40 years and John called saying he'd decided to run for president.
"This was in January 2002, and up to then, I'd really been focused on state races, so Washington was really something. I remember being like, 'There's Joe Lieberman!' ''There's Teddy Kennedy!' And the funny thing is, I suddenly found myself becoming friends with these people.
"I mean, Ted Kennedy's politics and my politics were coming from a dramatically different place, but once I met him and talked to him, I saw him in a completely different light. In fact, I called him shortly before he died, and he was very up front about what was going on and what he was going through.
"And I said, 'Well, look, I just called to say that for years I called you every kind of name in the book, but you won."
"He said, 'How did I win?"
"I said, 'Well, now that I gotten to know you, I love you.' He laughed at that. But seriously, he was one of the funniest and most wonderful people to be around that I've ever met. So meeting those people and the excitement of that and other things is what I associate with 2004 campaign.
"These people who appeared larger than life before then were just people, just like me," Saunders says.
"As for 2008, it was just hell. And I had already been through the experience once, so I knew some of the hardships I was going to experience. But that brings me back to Trump. For all his bluster, I think he was honest when he said running for president is a lot harder than he thought it was going to be.
"I mean, a presidential campaign is the most hellish thing that you can ever go through in your life. No sleep. Different time zones. You can't stay in the same hotel room two nights in a row. You're constantly on the move. You're trying to catch naps on the bus. I mean, it's awful.
"And then, as we talked about before, there is all the nastiness that goes along with it," Saunders says. "If there's anything Donald Trump has found out this year it's that running for president isn't quite what he thought it was going to be."
Saunders' thoughts back in the present, he says he thinks the high volume and often toxic Republican primary battle has benefitted Clinton by deflecting the national conversation away from her record and the ongoing FBI investigation into her use of a private email server while she was secretary of state.
In the end, though, Sanders doesn't think the certain refocusing of attention and the mudslinging of the autumn will be Clinton's undoing in the general election.
"I think so long as Trump stays on course and keeps talking about economic fairness, he wins ... I really believe that. I think what the electorate has told us to date is that they're willing to vote for Trump, with all the uncertainty that comes with that.
"In a contest pitting Clinton against Trump, a vote for Hillary is a vote for more of the same, and a large number of people are telling us they don't want that," he says.
"Which again brings up what I think is the biggest problem Hillary has in this race, when it comes time to vote for either her or Trump, I think a lot of Democrats will sit out the general election," Saunders says. 'Now, you'll have some, like I said, who will migrate to Trump, but then you'll have a larger number of Democrats those who say, 'I'm never voting for a Republican who'll simply say, 'I'm not voting for anyone this time. I'll wait for the next election.'"
In the alternative, he says, the domino effect in the upcoming general election could be that a lot of rural Democrats "what I call the screwed wing of the Democratic party," he says will split their tickets, voting for Trump for president and Democrats for the House and Senate.
Saunders says in his world, that of the rural voter, people look around and lament the demise of the textile and furniture-making and other industries that provided decent paying jobs and the promise of future jobs to succeeding generations of their families.
"Every one of those industries has been killed off," he says.
Now, Saunders says, the threatened industry is coal.
"I get asked from time to time, don't I believe in climate change? Aren't I for clean air and all that? And I do and I am. I am not a naysayer when it comes to climate change. But that said, right now I'm pro-coal because the people who live here need to have jobs," he says.
"Once my great party starts caring as much about the people at the bottom of the mountain as they do about the trees at the top, then we can talk about coal, and limiting its use," he continues. "But until then uh uh because they don't think about the people at the bottom of the mountain and their kids who need a job or are strung out on heroin or crystal meth. It's just a disaster.
"It's not about red or blue. It's about red, white and blue. It's about the country," he adds, growing more impassioned.
As sure as he is that Trump is positioned to win the primaries, get the nomination and prevail in the general election, Saunders thinks hard before offering an opinion on what a Trump presidency would be like.
"Hell I don't know. It might be great. It might be poor," he says. "The truth is I have no idea. But I do know this: with a Donald Trump presidency we will have change. He will shake up the system and right now that's what we need in America.
"To quote Jim Webb again, 'It's time to clean out the stable and just start over.' A lot of people believe that," Saunders says.
