So many on the British right were seduced by nativism. They took Trump's election, coming right after the Brexit vote, as a totem of a new global status quo.

It is fascinating to now see them dissemble, downplay, delete, deny and redefine their support in a desperate scramble to reformulate their position.

Some will have a true moment of reflection about where this kind of politics leads. Others will try to salvage their reputation, as they suddenly glimpse what a future evaluation of their behaviour will conclude. Others just want to preserve parts of the nativist project.

But in every case, we will remember: the people who saw a man who was demonstrably fascistic and swung with the wind, or even supported him. We won't forget that. It's a stain on your reputation forever.
