"A lot of voters who cast their ballots for Trump in 2016 soured on him and voted for Democrats in 2018 to keep him in check. Voting for Trump once is forgivable. People make mistakes and have flights of fancy and errors in judgment.

But if you still back Trump now in July of 2019, knowing what he is, knowing what kind of people you’re aligned with, that’s not on the opposition party–no matter how poorly or well it may be run, no matter how stodgy or populist it may be. That’s not on any politician or group. That’s on you. You’re responsible for every ugly word out of his mouth, and out of the mouths of all the Republican politicians protecting him. You have to own that. Your motives don’t matter.
Because ultimately, as Julius Goat said:

'“Historians have a word for Germans who joined the Nazi party, not because they hated Jews, but because out of a hope for restored patriotism, or a sense of economic anxiety, or a hope to preserve their religious values, or dislike of their opponents, or raw political opportunism, or convenience, or ignorance, or greed.

That word is “Nazi.” Nobody cares about their motives anymore.

They joined what they joined. They lent their support and their moral approval. And, in so doing, they bound themselves to everything that came after. Who cares any more what particular knot they used in the binding?”'
