If Biden wins the nomination can he unite the party by picking Bernie Sanders as VP?

58. Biden wanted Warren for his running mate in 2016 if he'd run.

Reportedly, Warren was THE choice for Biden, and they even met to discuss the possibility.

But that intractable faction of Sanders' supporters who reject Democrats won't vote for her. There aren't that many of them, but few would vote for Biden if Sanders were the running mate. They've all promised to once again decamp to Trump or whoever can cause us trouble after Sanders is out of the race.

Remember, in 2016 these people were outraged by Sanders' long-delayed, reluctant endorsement of HRC, and they noisily and angrily rejected his leadership when he issued his statement that they should support her. Instead, they launched the "Demexit" movement to try to get people to leave the Democratic Party. Their specific purpose was to destroy America's liberal progressive party and throw the nation to the mercies of the Republicans.

These are destroyers, not builders, and not about to unite.

On the plus side, Sanders' Democratic supporters, easily the larger faction, will once again support our nominee, period. He's their current preference, not their cult leader or weapon.
