This is very important to keep in mind I think. Like all populists he is deeply corrupt and a political outsider who doesn’t care at all about ideology. But he still needs the political system to prop him up. And he can play them easily because as we’ve seen they will tolerate anything to get their agendas passed. Pence et al. are actually much more dangerous than Trump.
That’s why I think it would be wise to move the focus of the protests away from Trump the person to those Republicans and their fringe politics, if only for the time being. They are much more vulnerable, too, despite their current majorities.
