fskimospy, those who identify with Trump have been corrupted by their own Egos. Its job is to constantly make excuses to make one's ID feel better. To live with one self, no matter the departure from reasoning or logic. One's ID defines how far into madness the Ego must take them, depending on the subject of that ID. Given that it is Trump who became head of the Republican Party - that is an incredible boon to mental illness in this country.
Yes, they should have been revolted by him - but Trump is a populist and he sang the right tunes. He successfully sold his ID to them, and now their minds are lost unto madness. Reasoning with them is difficult, if not impossible, due to the mental barriers that now exist. The more you push Trump the more you effectively push them. It's not merely Trump's honor or ID at stake in these proceeding, the voters feel it is theirs as well. Thanks to the sunk costs model they go all in on defending "themselves" from outside attack.
This is beside right and wrong or rule of law. It's gut feelings. It's Pavlovian response. You push Trump them, they push back.
