I have come to believe that many conservatives possess what I once thought was a left-wing monopoly — a utopian streak. Trump is too far from their ideal leader to be able to support him.
There is also a cultural divide. Anti-Trump conservatives are a very refined group of people. Trump doesn’t talk like them. Moreover, the cultural milieu in which the vast majority of anti-Trump conservatives live and/or work means that to support Trump is to render oneself contemptible at all elite dinner parties.
In addition, anti-Trump conservatives see themselves as highly moral people (which they often are) who are duty-bound not to compromise themselves by strongly supporting Trump, whom they largely view as morally defective.
Finally, these people are only human: After investing so much energy in opposing Trump’s election, and after predicting his nomination would lead to electoral disaster, it’s hard for them to admit they were wrong. To see him fulfill many of his conservative election promises, again in defiance of predictions, is a bitter pill. But if they hang on to their Never Trumpism and the president falls on his face, they can say they were right all along.
