Who has the best chance of winning the nomination and to beat Trump in 2020?

I think it will be a dark-horse candidate. So, of all of these, the most likely is Deval Patrick.

By the way :

WI: Mark Zuckerberg

Get used to it folks.

I'm not a native speaker, what does WI stands for here ? (I assume it's not Wisconsin.)

Of those on the list, Booker (is Black), followed by Sanders (winner of the White vote in the 2016 Democratic primary).

I think Sherrod Brown will take make of the prior Sanders voters.

His voice sounds really terrible, though. I'm actually afraid he has some health problem, it can't be normal.

I think Chris Murphy's ultimate ambition would be Health Secretary. He cares about Mental health a lot (makes sense, because of Sandy Hook).

Chris Murphy is very intelligent and seems to care about his constituent. However, he lacks this brilliant touch that many look for in a president. He is not a genius lawyer or a cunning businessman, nor an extremely charismatic leader that everyone instantly love. People tend to wait for the perfect president, like some type of providential man. If this fad die down, maybe he will reconsider. He could also be a good VP pick, and from there end up President, who knows. (Also, he reminds me of Al Gore.)
