Could any other Democrat have won the presidency besides Joe Biden?

Bernie Sanders could not have won enough moderate voters. He is too far left. Biden was just the right person. Trump knew that. Why do you think he worked so hard and even got himself impeached trying to smear Biden?

A gorilla would have beaten Traitor Trump 

In this election, I think anyone the Dems could have put up would have beaten Trump.  When an incumbent president is running for re-election to a 2nd term, the election is always about him, whether he deserves a 2nd term.

Biden was nominated because it was 'his turn'.  We've had a number of candidates like that in recent decades.  Barry Goldwater, Hubert Humphrey, Bob Dole, Hillary Clinton, Mitt Romney, etc.  Most of them lose.  Biden was the exception because he was lucky enough to run against the Trump Trainwreck.

No other Demonrat could have defeated Trump in 2020 and the only reason Biden won is because Demonrats successfully weaponized the Coronavirus against Trump. 

Sanders or Bloomberg.   Warren was good  but I don't think America is quite ready for a female president.  

Yes, Sanders appeals to the far left, and federal school kids that were taught W.Wilson & FDR are hero'S, when they are Zero's.

God Bless President Biden for saving The USA from Dementia Donnie!

Sure. But America chose Biden. Lets help him help ourselves.

As we know, Bernie Sanders was the actual favorite
