The team that brought you the George W. Bush administration in 2000 has gathered behind a new candidate: Bernie Sanders.

A host of prominent Ralph Nader backers has joined team Sanders in 2016, excited by his message discipline and aggressive fight against the establishment powers that be.

In the Democratic socialist from Vermont, they see a flag-bearer for the same issues, while the Democratic establishment views him as a persistent pest who is raking in money by the fistful without a clear and obvious path to the nomination.

And the same way that Nader’s staunchest supporters had no kind words for the eventual nominee then-Vice President Al Gore, some of Sanders’s surrogates are spending their time bashing Hillary Clinton, making it even more difficult for the party faithful to rally around him.

Throughout Nader’s consecutive failed presidential bids, he picked up a cadre of high-profile endorsers, ranging from actress Susan Sarandon to academic Cornel West. The rest of the roster backing both men includes actor Danny Glover, former National Nurses United Executive Director RoseAnn DeMoro, musicians Ani DiFranco and Bonnie Raitt, country singer Willie Nelson, and Ben Cohen, one of the founders of Ben & Jerry’s, just to name a few.

“There are some pretty obvious parallels,” Oliver Hall, Nader’s lawyer and longtime friend, said in an interview with The Daily Beast.

While the players on the bench supporting these candidates are remarkably similar, so far Sanders hasn’t drawn the collective ire of the Democratic Party quite nearly as much as Nader did. His campaign did not respond to a request for comment from The Daily Beast.

After all, many personally blamed Nader for pulling Democratic votes away from Gore in 2000—ushering in Bush.

It’s tough to blame them for being angry. Bush edged out Gore by 537 votes, while Nader—the Green Party candidate—took over 97,000 votes in Florida, which Democrats thought could have tipped the scales in Gore’s favor.

The spoiler effect, a term ascribed to 1992 candidate Ross Perot, was redubbed as “The Nader Effect,” used as shorthand for a candidate that is going nowhere spoiling an election for a like-minded but more viable party nominee.

Nader has been adamant that he is not the one to blame, writing in 2004 on his presidential campaign site that his voters wouldn’t have swung the election in Gore’s favor.

“In the year 2000, exit polls reported that 25% of my voters would have voted for Bush, 38% would have voted for Gore and the rest would not have voted at all,” he wrote.

The 2000 campaign efforts (some of which were led by his own supporters) to get Nader to drop out fell on deaf ears.

And 16 years later, a much more successful candidate has no interest in cutting his bid short either—despite almost daily urging from the Democratic establishment.

But still, the longer Sanders has stuck around the more he appears to get under Hillary Clinton’s skin.

Now the winner of 14 states, including a surprise victory in Michigan, Sanders is frequently painted as a message candidate spoiling the prospects of an establishment Democrat looking to finally secure the nomination after falling short eight years ago.

His staunch opposition to the Iraq War, something for which Clinton voted, and support for a single-payer health-care program mirror some of the central tenets of Nader’s campaign.

Hall told The Daily Beast that the similarities between the candidates are apparent and even now he’s still tired of hearing that the latter is the reason Bush won in 2000.

“It’s ridiculous and pathetic,” he said in a phone interview. “If the Democratic Party is a serious organization, they need to tolerate free discussion of ideas.”

He contended that the same people who have accused Nader of indirectly leading the United States into its worst war since Vietnam are the ones imploring people to vote for Hillary Clinton this year.

“When Nader ran as a third-party candidate, everybody attacked him,” Hall said. “Now they’re attacking Sanders for running as a Democrat.”

And as Sanders continues to exceed expectations in the primary, currently leading Clinton by a small margin in Wisconsin—the next contest—Hall questioned the former secretary of state’s strength as a candidate.

“How good of a candidate can Hillary Clinton be if she can’t handle debate in the primary election process? That’s the entire purpose of a primary election.”

And his endorsers have taken note.

West, a prominent academic and progressive Democratic stalwart, backed Ralph Nader in 2000 before giving Sanders his blessing in 2015. Once Gore was the nominee, he chastised him for picking Sen. Joseph Lieberman as his running mate given his opposition to affirmative action. West referred to it as “an act of disrespect to the black community,” according to a 2000 article in the Chicago Tribune.

Earlier this year, West wrote an op-ed for Politico describing Sanders as being “better for black people” than Clinton.

West has not responded to a request for comment from The Daily Beast.

Sarandon, another Sanders backer who recently drew controversy for suggesting that Republican presidential candidate Donald Trump might be ultimately better for the United States than Clinton, was also all in for Nader in the past. She served as the national co-chair for Nader’s steering committee in 2000 and was named as a plaintiff in a lawsuit he filed against the Federal Election Commission which alleged that corporations sponsoring debates could constitute as illegal corporate campaign contributions.

Documentarian Michael Moore also endorsed both candidates. In September 2000, he appeared at a fundraiser upon the Green Party candidate’s behalf, dispelling the idea that Nader was a spoiler in the race.

“A vote for Nader is a vote for Bush?” Moore said at the time. “No, a vote for Gore is a vote for Bush. A vote for Bush is a vote for Bush. A vote for Nader is a political Molotov.”

In 2000, Sanders publicly vouched for Nader himself, while the latter campaigned in Vermont.

“He’s an old-fashioned guy who believes that maybe the ordinary people should be running this country rather than the multinational corporations,” Sanders said in introducing Nader at an event, according to an AP story at the time.

Sanders’s national spokesperson Symone Sanders also previously worked as a communications officer for the Ralph Nader-founded organization Public Citizen.

Sanders changed his tune by 2004, though, when Nader tried to run again, saying “virtually the entire progressive movement is not going to be supportive of Nader,” according to an AP story.

“We’ve got to come together to defeat George Bush, we have to develop a strong progressive movement to make sure we make the changes in this country that we need,” Sanders said in 2004. “But our main task right now is to defeat Bush and I think Nader’s effort could have some impact in dividing up that vote and that’s a negative thing.”

Nader himself did not respond to a request for comment from The Daily Beast but he has expressed support for Sanders’s candidacy and his ideas.

The animosity between Nader and Gore supporters that bubbled up in the 2000 general election is already stewing in a similar capacity in the 2016 Democratic primary with surrogates like Sarandon and actress Rosario Dawson criticizing Clinton and the big-money interests they contend she stands for.

“Shame on you,” Dawson said referring to Clinton at a recent rally in New York. “I don’t have to vote against someone; I can vote for someone who’s on our side.”

She went on to criticize President Obama at a Harlem town hall days later, suggesting that he wasn’t able to keep up momentum to elicit a big turnout in the 2014 midterm elections.

Another Sanders surrogate, rapper Killer Mike, got into similar hot water for quoting activist Jane Elliott’s line in February saying: “A uterus doesn’t qualify you to be president of the United States.” Implicit in the remark was not sexism, but rather that gender should not determine who one votes for.

The difference, of course, compared to the fervor around Nader is that these conflicts of opinion are not necessarily going to negatively impact the chances of a Democratic president being in the White House next year.

But from the start, Sanders’s campaign was concerned about appearing like just another Nader.

“The one thing he’s determined not to do is to be another Ralph Nader,” adviser Tad Devine said in April, 2015 as Sanders was preparing to announce his candidacy. “And the only way to avoid doing that is to avoid being a third-party candidate from the left in the general election.”

Time will tell if that promise holds up.
