I believe the comparison comes more from being an outsider, and somewhat of an eccentric personality. I'll fully admit I think "Trump" has become more of a buzzword than anything else.
Politically it's difficult to make a direct comparison as there's such a small track record. It'll be...interesting to watch what happens. Some of his initially moves will 4x the monthly inflation to over 40%, which will bump it to over 200% annually (I'm not an economics major by any means, so maybe these initial moves will have longer-term benefits), but they are attempting to pass regulations that strip the rights of protestors. For me it is laws like that that give me the greatest concern.
