There was a blue wave, of sorts. As I write the Democrats have taken the House. That puts a spanner in some of the works of Trump. But the Senate has a Republican majority, despite the supposed blue wave. And some profoundly nasty Republicans were elected.
I welcome the shift to the left that is implied by the policies of some of the candidates who were elected for the Democrats. There is also welcome diversity amongst them. But let's not get overwhelmed with excitement: Trump has not released a wave of revulsion. It's more like a trickle of opposition. And that's very worrying.
