With one notable exception, everything about Trump’s candidacy is an affront to the Christian Democrat faction of the GOP. His flashy lifestyle, crass materialism, arrogance, bigotry, and antipathy to society’s “losers” are antithetical to the one world type of conservatism that the CDs espouse. The exception is abortion; his earlier pro-choice statements notwithstanding, there is no reason to doubt that he would appoint judges who would restrict women’s reproductive rights to the maximum extent feasible, which is a matter of great importance to many CDs.
What’s a poor CD to do, then? They can’t even avoid the issue by voting for Johnson, like the Conservative Libertarians. My best guess is that the vast majority of them will suck it up and vote for Clinton, because while she may be pro-choice, she won’t endanger their lives, liberty, and property.
