It was clear 18 months/2 years ago that Biden wasn't up to itIt’s very easy to say that the democrats had a bad campaign or Harris was the wrong person.
But the real story is the popularity of Trump. It would have taken someone like Obama to beat Trump this time round. He has won big. Trump attracts blind love or profound hate from the electorate. He found a way to tip the scales in a divided country. I don’t think it was down to what the democrats didn’t do, I think it was about what he did do. He promised wealth. Wealth to many voters who put money above anything else such as honesty, judgment or just plain human decency. He’s played a blinder.
The search should have started then and a proper election for the nomination should have been held.
Trump is a vile human, they played on this way to much, people know he is, that's not going to change voters minds.
