It was clear to me why people voted for trump the first time round. (Although, many experts believe it was more about voting against Clinton than for trump.)

He was an outsider/wildcard/Maverick and perceived smart businessman so his promises to clean up the corruption seemed more plausible than the entrenched status quo.

Now that his lack of business acumen, lack of general intelligence, non-existent diplomacy, zero empathy, and pure personal greed mixed with nepotism and corruption has been laid bare, I understand those who plan to vote for him next time round very little except through the lens of identity politics and hate/racism/xenophobia/epistemonophobia.
