Personally I hated the birther thing as I thought it was stupid, and to be honest I think he's fairly scummy. With that being said - I try to look the best I can at policy more than anyone's personality. Not that I agree with ALL his policy, but for as long as I can remember we've had politicians handing crumbs to people (usually in the form of "social" policy), saying the right things, "behaving" the right way in exchange for slowly eroding the liberties and economic mobility as everyone else. And even if he didn't pan out ideally by any stretch, at this juncture in the U.S., I think alot of people felt like we at least had to TRY with someone that wasn't someone that's been in politics for a long time, towing the typical party lines while slowly lining their pockets and that of their Ilk. Even if misguided in my opinion, I get why people would prefer Trump AND Bernie over other candidates with regard to cultural change in Washington; although Bernie's looking more establishment these days.
Also that tweet alludes to my point. Why are we listening to the same entrenched politicians about what's good/bad? It's their decisions on good/bad that have lead us down this slow and steady path. And that's part of the nefariousness, they do just enough to make things worse but not too much that it effects their electablility, and slowly but sure the country starts to become less free, less prosperous for the general population. They're basically playing into Hedonic adaptation. And it's working. Each year won't look too much different from the year before or even 5 years before, however over 20, 30 years, you'll see where we were and where we're at and wonder how things have changed so much, for the worse, even if we have increases in certain material "comforts" (see: distractions).
