That is one of the awful things about this presidency. It is the endless contemplation of vile behaviour. Of a dead mind in action. It saps the joy from life even to think about Trump. It's destruction all the way down, even as, somehow, the US judiciary and Obama's economy have spared America from what might otherwise be the case.
I do think Biden is slightly wrong about another four years of this president. The country will survive if it has a Democratic senate and house. And there will be an opportunity to build a newer, better America afterwards.
