You have hit the nail on the head. The way to defeat Trump is to energise the left and the young people. They are not energised by simply making Trump the bogeyman no matter how bad he is. Who wants to live in a country where life is only better than terrible?
If Trump gets re-elected it will be the fault of the Democrats. They need to be more afraid of the electorate than they are of Trump. Let Biden understand what it will be like when everyone hates his guts because he put his donors ahead of the American people and got Trump re-elected
