Who is most likely to win the 2020 Democratic presidential nomination?(Aug 2017)

If Sanders runs, I think he's going to win.

I think he occupies a portion of the electorate that no other candidate, excluding Warren, can touch. It will probably be enough to get him the nomination if there's a really crowded field.

I don't know why people think 2020 will be the same as 2016.

Sanders is popular, has significant name recognition, a clear message, he's been building a relationship with the DNC chair, and the democratic establishment is moving in his direction. Bernie Sanders is the Hillary Clinton of 2020. I would be really surprised if 55% of primary voters voted for Clinton because they're opposed to Sanders and socialism, and that the majority of those voters couldn't flip to Sanders.
