Democrats are in a unique position where black voters will probably support Bernie (and many already do except in the South), but many white voters won’t support Biden. The black vote is honestly one of the hardest things to predict in American politics because Black Americans have been so disenfranchised. Latinos also support Sanders in huge numbers right. Plus, Sanders carries an insane amount of the under 45 vote, that the Democrats also can’t afford to lose. If Biden wins, I think the Democrats lose. If Sanders wins, it’s close. If Warren wins, we’re in the White House.
