Don't understand how Ralph Nader's faced 20 years of abuse for winning 1.63 percent of the vote in Florida, but it's off-limits to suggest Elizabeth Warren staying in for no reason to take 10-20% of the vote in various Super Tuesday states had an effect on the result.

The legacy of Warren's campaign is that she helped cripple any remaining momentum Sanders had when he desperately needed it. Look at these numbers, esp Texas (the last one) and imagine if the roles were reversed. Would progressives be as kind to Sanders staying in?

Super Tues was the end of the primary. After Sanders' early wins, voters flirted with defying a relentless media narrative, but Biden winning SC then Super Tuesday gave them permission to go back to him. Wouldn't have happened w/out centrist consolidation and progressive split.

There's tactical things Sanders camp should've done in hindsight bla bla bla, but he was polling strong everywhere up until SC when all those things were true. Centrists consolidated; progressives, for some mystifying reason, didn't. It's not really more complicated than that.
