Trump’s ban of travelers from seven Muslim countries spawned a large backlash, showing that “the resistance” is still a thing. I suspect it will continue to be a thing, because Trump is going to do much which enrages people who already believe he is a fascist.
It is little commented on now, but when Bush was ramping up for his invasion of Iraq, millions of people came out against it, world-wide. Most US allies of any significance–apart from Britain–refused to participate. The war went ahead anyway, and in its shadow there was resistance. I was part of that, the Netroots.
The Netroots opposed Bush directly when possible, and it also sought to make the Democratic Party better because we had noticed that enough Democrats (and in many cases almost all) Democrats had signed off on the worst parts of Bush’s regime. Gore, had he been in power, might not have been quite so bad, but the Democrats weren’t really opposing Bush strongly, and some of them were absolutely terrible–straight-up collaborators. Joe Lieberman, for example. (Who was also Obama’s mentor in the Senate.)
