Latinx are overwhelming swinging to Sanders (per your link), people of color swing Biden due to his riding on Obama's coat tails [1] (IMHO; he has no policies that benefit them with his "status quo" stance).

If Biden runs, Trump wins reelection. Not enough voter support for Biden besides older voters and people of color, younger voters will sit out before voting for Biden in a general election. That's not my opinion, that's what the polling data shows.

You see black people [on the ballot], you see Democrat, you vote straight party. You’re not used to seeing 10 damn candidates in the first place,” added Robinson. The menu of choices plays to Biden’s benefit because he’s a known commodity, Robinson said.)

Young people don't vote, so no one cares what they think. Latino's and African American's will vote for Biden since Trump is pretty damn racist and if they don't, they are basically screwed for another generation. Minorities don't have the luxury of waiting for the perfect candidate like White College Kids can.

¯\_(ツ)_/¯ I'm not here with opinions, just data. I'm not responsible for the choices of others. Everyone is at the mercy of swing states and voting cohorts that vote consistently. If you're not a majority of some sort, and not in a state with an outsized amount of influence due to the Electoral College, it's very unlikely you get what you want.

There are still many Latinx [1] and people of color [2] voting for Trump (or desire a candidate besides Trump and Biden), despite his character. Never underestimate a Cult of Personality.

And yet, his support among this crucial portion of the electorate remains surprisingly consistent. After the 2016 election, exit polls analyzed by the Pew Research Center showed that 28 percent of Latino voters supported Trump; today, 30 percent support him.")
