The democrat party uniting behind Biden will solve nothing. The fundamental issue is not a disunited party turning off voters , the issue is Bidens health.
To win the election the democrats need to convince the swing voters and undecided middle ground.
Bidens health issue aren't going to go away. In fact they can only get worse - people don't bounce back from age related decline.
Trump lied repeatedly during the debate, yet no one has taken him to task over it because all anyone can talk about is Biden's health.
Biden won't just lose the presidency, but will also impact all the down ticket candidates for the senate and house. The real risk here is handing Trump the Whitehouse and congress if nothing is done.
Please stop defending the madness. He needs to be replaced before its too late, for the greater good of the USA and the rest of the world. He was a good president but he is not the candidate for this election. Don't hand Trump the presidency by allowing such a vulnerable candidate to run.
