Warren 2020

Since it's the primary, I'm going to speculate a little bit here.
The polls, even the ones showing Biden still holding a commanding lead, show Warren gaining ground.
A large part of Biden's support is from people who view him as the most electable candidate. If Warren continues to
cut into his lead and the perception of his "electability" is called into question, I expect a moderately sized exodus from Biden to Warren.

My other prediction is that without a win or top 2 finish in the first 3 contests, Bernie will stagnate. I'm sure he will
hang in until the bitter end, but he'll start bleeding voters that are mostly going to go to Warren.

I think Warren has the most wiggle room in the first few contests.
