I wouldn't think so, Donald Trump isn't just a person to vote for, he represents going against the establishment of the past.
I am not a fan of Trump, but I won't demonise anyone who is.
Many people won't see Joe Biden as any different than Hillary Clinton. He represents the same stuff as the Obama establishment, which is good for some people, but terrible for people who don't like it.
Plus Joe Biden does act inappropriately, there's lots of footage, that many consider creepy. I am not saying that Trump isn't inappropriate, he is and he has been in the past.
However, Trump never pretended to be a super-clean politician, if anything, he knew people would criticise him and he embraced it more.
Joe Biden does pretend to be super-clean, he pretends to be a morally pure person, which he clearly isn't.
I wouldn't be surprised if lots of people vote for him, simply because they hate Trump.. but those people are going to vote Democrat, regardless of who the candidate is.
I don't think enough people will vote for him or any of the current Democrats, especially now that Howard Schultz is running as an independent and may split the vote.
From my perspective the Democrats are competing against one another and don't seem united at all. Their policies are also mostly based in identity politics, which many people despise.
No, I don't think Joe Biden is the end for Trump.
