2020 Candidates... WIN OR BUST?

I have many thoughts on who should be the nominee in 2020. There is certainly a high likeliness of Bernie being our candidate, and there are many things to like about him.

But am I the only one who thinks the only way we win 2020 is a centrist Dem? Biden being a prime example. I feel like this is the only was we win back those rural voters who voted for Obama then went to trump.

What are your thoughts?
