I disagree about them being the same. They do both suck--on that we agree. But they are not the same--they suck in much different ways, although for some similar reasons (human nature to hoard power).
The thing about Trump is that you have to classify him as Republican based simply on the fact that those that are holding him up are Republican elected officials, members of the public supporting are typically Republican (Texas is my reference point for this, YMMV), and Republican leadership in Congress, including Committee chairs, are disinclined to offer any type of check on his efforts to date. I agree he is far from any kind of classical GOP/conservative definition, but he has clearly chosen a tribe for the time being and that tribe has accepted him, by and large, as one of their own.
And you know what I mean by democracy (little "d" democracy). John Q. Citizen does not know or honestly want to discuss the subtle intricacies of constitutional republics vs. true-blue democracy. You and I will enjoy conversations like that, but anybody that works in planning/government is wired different to enjoy that kind of thing. You run around to them correcting that and let me know how it goes and how many times they grump about being smug or elitist (I know you aren't, but you'll get called that). The point of my statement is that gerrymandering is the source of the conditions that lead to populist uprisings in this country, not to debate the finer points of political system description. Gerrymandering occurred through desires to consolidate power. Term limits won't fix that--you'll get into a weird world of endorsements/naming heirs and a rebirth of machine politics. District reform has to occur first.
The most interesting reading I've seen on the subject though is political scientists beginning to discuss a "post-party" America in which that system begins to break down and/or new parties emerge. Basically, it is a super nerdy and somewhat academic discussion of the strength of populism to potentially overcome the party apparatus, discussing the psychology and sociology of what took place during the election and what happens when parties lose strength in gerrymandered circumstances. Talks a lot about echo chamber politics and dismissal of anybody that disagrees with you, and the role that may eventually play in party reform, future elections, etc. Google around and you'll find some interesting reading.
