for trump is a dumb bigot. Some simply preferred having a repub in the WH and trump seemed to be in line with some things more traditional repubs support, like lower taxes, less regs, and repubs on the USSC...and some just refused to support a Clinton. I may disagree with them but those are positions that can be rationally debated.
So they closed their eyes, held their tongues, took some anti-acid to quell that sick feeling, and voted against Hillary or for the repiub candidate.

But at some point, the character of the prez over rides the pieces of bread he tosses to them (or paper towells) . he is not fit for office.
