I've been heartened by the feverish activity of the resistance/reform groups that have formed so quickly to oppose to this administration and the harm it seems intent on doing.  The reality may be that active resistance may not accomplish everything it seeks to do, but it will serve at least a couple of important purposes: to unify those who find Trump's presidency and his administration's goals abominable and untenable;  to erect as many legal and procedural roadblocks as possible, including the very real threat of upsetting the Republican apple cart in 2018.  

These efforts won't protect us against the worst Trump can do in his peripatetic foreign policy decisions, including his use of military "solutions," but they may keep some of the Democratic programs at least on life support.  I think the Left has been energized by the specter of right-wing control, and that's not a bad thing.
