The last three standing are likely to be Biden, Warren, and Sanders. How will that turn out?
It depends on whether Warren succeeds in portraying herself as the sensible one in the middle, or whether she continues to compete with Sanders solely for progressive votes. If the former, she probably wins; if the latter, Biden wins, because his lane is wider, and he will have no competition. It’s that simple.
Is Warren capable of moving to the middle? Sanders is making it easier for her by drifting even further to the left. There is definitely room there if she plays her cards right, but it will require some tactical and rhetorical dexterity. It certainly hasn’t happened to date. We’ll see.
