Who will be the Democratic nominee for president of the United States in 2020?

Will it be Sen. Bernie Sanders, who came second in 2016? A growing number of voices, both liberal and conservative, loudly disagree. “I think his moment is passing,” says Daily Kos founder Markos Moulitsas. “Bernie Sanders is Shrinking,” declared a headline in the Weekly Standard (only a few weeks before the neocon magazine, ironically, closed down). “Democrats will soon decide that Bernie Sanders is an indulgence they cannot afford,” opined The Economist.

Yet the arguments that these diverse critics offer against another Sanders bid for the White House seem to be either overstated, irrelevant, or flat-out false. Consider five of the most common criticisms of the independent senator from Vermont:

He’s Behind in the Polls

It is Joe Biden, and not Bernie Sanders, who has been ahead in almost all of the opinion polls so far. A new survey out of Iowa finds the former vice president leading the field with 30 percent support from Democratic voters, followed by Sanders far behind at 13 percent, and rising star Beto O’Rourke, snapping at his heels with 11 percent.

Other polls have produced similar results. But not all of them. A new straw poll of progressives by Democracy for America, released on Tuesday, gave Sanders a 21-point lead over Biden.

But here’s the bigger question: Are the polls really relevant at this stage? The election is 23 months away, and none of the main runners and riders have formally announced that they’re even running yet.

For comparison, guess who came top in a CNN survey of potential Republican presidential candidates in December 2014, 23 months before the 2016 presidential election? It was Jeb Bush, at 24 percent, with a double-digit lead over his nearest rival, Chris Christie. Ted Cruz, who would end up coming in second in the 2016 GOP primaries, was eighth place with 4 percent. Donald Trump’s name didn’t even make the list.

He’s Too White

“Mr. Sanders fought Mrs. Clinton to a draw among white voters,” concluded an examination of the exit poll data by the Wall Street Journal in 2016. “The decisive edge for Mrs. Clinton: She won African-Americans by more than 50 percentage points.”

Hence the longstanding narrative that Sanders has a problem with black folks.

Except … that’s not quite true. A whole host of prominent African-American figures — including Keith Ellison, Cornel West, Ta-Nehisi Coates, and Spike Lee, among others — backed Sanders over Hillary Clinton in 2016. Former Ohio state Sen. Nina Turner and then-press secretary Symone Sanders were key surrogates of his.

In 2016, the Vermont senator’s problem was with older black voters — not black voters per se. In fact, according to polling by YouGov, Sanders “fought Clinton to a near draw with people of color between the ages of 18 and 44,” and according to polling by GenForward, “among African American young adults who indicated they voted in the primaries, a majority, 54 percent, said they voted for Bernie Sanders.”

Since 2016, Sanders has worked hard to make further inroads into African-American communities, helping to bolster the insurgent campaigns of up-and-coming black politicians, such as Florida’s Andrew Gillum. Last week, a CNN poll found that Sanders had a higher approval rating, at 58 percent, with nonwhite voters than any other major candidate. So, will this latest survey put an end to the black-voters-dislike-Bernie canard? I doubt it. As my colleague Briahna Gray has observed: “Bernie Sanders doesn’t have a black problem — he has a pundit problem.”

He’s Too Old

Come Election Day, November 2020, Sanders will be 79 years old, which would make him the oldest person to ever run for the White House.

Yet his likely Republican opponent, Trump, will be the previous record-holder. He was 70 in 2016 and will be 74 in 2020. Yes, the overweight sitting president, who eats junk food, doesn’t exercise, and refuses to release his medical records.

In terms of the Democratic primaries, Sanders will be 79 in 2020, but Biden will be 77 and Elizabeth Warren will be 71. Oh, and did you know that Speaker-designate Nancy Pelosi and her top deputy Steny Hoyer are both older than the Vermont senator?

So why should his age be held against him?

He Isn’t a Democrat

So what? He may be an independent but he caucuses with Senate Democrats and is their chair of “outreach.” He won 13 million votes in the 2016 Democratic primaries.

Despite refusing to join the Democrats in the wake of the 2016 election, the party’s base still adores him. As of October 2018, he had a whopping 78 percent approval rating with Democratic voters.

He’s a Socialist

Again, so what? While it may indeed harm him in the presidential election, with a clear majority of Americans claiming that they wouldn’t vote for a “socialist,” it certainly won’t hurt him in the Democratic primaries. According to polling from Gallup, a majority of Democrats have a positive view of socialism — in fact, Democrats have “a more positive image of socialism than they do of capitalism.”

Even in the presidential election itself, I suspect Republicans would find it difficult to demonize Sanders with the S-word, having deployed it to try and smear the centrist Barack Obama for eight long years. Going beyond the label itself, Sanders’s left-wing policy agenda is hugely popular with the electorate — even with hardcore Republicans.
