Progressives won't win against Trump

Why?

Because this isn't a fair fight to begin with. It is likely the single most corrupt election the U.S. has ever seen so far with nations bribing Trump and his government officials right and left from around the world. In other words, the world will elect Donald Trump if everything presently remains the same but not through the electorate.

So, the best hope is Biden who is a moderate. Biden is the ONLY candidate that Black moderate and conservative voters would consider voting for and the ONLY candidate that Independents would consider voting for either and NO ONE can win the election without them.

IF a progressive runs the Black Conservative and Moderate voters and the independents won't show up at the polls at all for either Warren or Sanders.

This is just a pragmatic fact of life.

Therefore, the ONLY candidate capable of winning against Trump realistically is Biden. All the rest would lose.

However, I think a Biden-Warren Ticket or a Biden-Harris ticket might win too which would be somewhat similar to the McCain-Palin ticket of a while back too.

Trump knows this too which is why he got impeached already by trying to interfere with Biden's candidacy.

With a Biden Warren Ticket you would eventually possibly have the first woman president and with a Biden Harris Ticket you would have the first Black Woman president eventually possibly too.
