That announcement ends a five-year run that encompassed two presidential campaigns for Sanders. He finished second in both races — losing a protracted delegate fight to Hillary Clinton in 2016 and again watching as the Democratic establishment pick, former Vice President Joe Biden, again surpassed him in 2020.
So, what then did Sanders prove over the last half-decade of seeking national office? And what did he not?
Let’s take the first question first.
What Sanders understood long before Clinton, the Democratic establishment and much of the media, was that the base of the party was far more liberal than its top leaders in Washington. And had been for some time. And that base was sick to death of having their priorities ignored or shelved in pursuit of so-called “pragmatic” solutions.
Sanders channeled that frustration and alienation in two critical ways.
First, he unapologetically embraced longtime liberal policy totems like single-payer health care (“Medicare for All” as Sanders dubbed it), a $15 minimum wage and putting the threat of climate change front and center in the national debate.
Second, Sanders was, oddly, the perfect messenger for not only those liberal policies but for liberal voters too. His unkempt appearance, his wrinkled suits, the volume — loud! — at which he spoke all fit the un-politician that so many Democrats were looking for.
His age — Sanders was 73 when he first began running for president — also played a role — in a positive way. This was a man who, in the eyes of Democrats thirsty for someone who actually had long-held principles, had been saying the same stuff for decades. He was no recent convert to being a liberal. He had been waiting for people to come to seeing the world he did for lots of years.
While Sanders wound up losing the delegate battle to Clinton in that first race — his side would say superdelegates being factored into the count led to the unfair perception that he could never beat her — there’s no question that he vastly outperformed expectations and, in so doing, installed himself as a mover and shaker within the party on both the policy and political fronts.
The following year, in one of the biggest upsets in modern political history, an unknown New York City bartender named Alexandria Ocasio-Cortez beat Rep. Joe Crowley, a member of the Democratic leadership in Washington, in a House primary. Ocasio-Cortez ran, like Sanders, as an avowed democratic socialist and cited Sanders as her inspiration.
Combine Sanders’ surprise showing in 2016 with AOC’s earth-shaking upset in 2018 and it seemed clear that liberalism — and anti-Washington establishment sentiment — was on the march within the Democratic Party.
And so, when Sanders got into the 2020 race he did so as a front-runner — or co-front-runner alongside Biden, the clear establishment favorite.
Sanders faced questions about whether he could repeat his 2016 performance with a much-larger field and with lots of other candidates trying to occupy his space on the far left of the party. For a time in the summer of 2019, Massachusetts Sen. Elizabeth Warren appeared to have wrestled the mantle of liberals’ favorite liberal away from Sanders as she soared to the top of polling in early states and nationally.
But Sanders persisted. And the army of supporters that he had built in the 2016 race — and carefully cultivated in between the races — never abandoned him, producing tens of millions in campaign contributions and an incredible grassroots organizing base.
He came within a whisker of winning the Iowa caucuses. He won the New Hampshire primary. And then he won the Nevada caucuses, at which point it appeared as though Sanders was going to be the Democratic nominee, with only Biden in South Carolina in his way.
Which brings me to what Sanders’ two presidential campaigns didn’t prove: That a liberal’s liberal could win a majority of the Democratic presidential primary vote and be chosen as the party’s nominee over a more centrist candidate with establishment backing.
What Sanders had was a hugely enthusiastic base of supporters that included young people, liberals and Hispanics. What Biden had was overwhelming support among African American voters and solid backing from moderate and conservative Democrats.
As was the case in 2016 — when Clinton had the majority of non-white voters within the party — the Sanders coalition was simply not as big as his opponent’s. And — and this is critical — Sanders was never really able to convince those skeptical of him that he could and would represent their interests as the nominee. Too many Democrats viewed a vote for Sanders as a risk rather than as an opportunity. And it doomed him.
It’s possible that come 2024 or 2028 someone in the Sanders’ mold — Ocasio-Cortez turns 35 and could serve as president in October 2024 — will find a way to solve the problem that the Vermont democratic socialist couldn’t over the past five years.
But that’s a debate for the future.
In the present, what Sanders proved is that while there is a significant bloc of voters in favor his liberal solutions to America’s problems, there still aren’t enough to elect someone like him as the Democratic presidential nominee.
