I completely understand why some conservatives are horrified at the prospect of Donald Trump being the Republican nominee for president. I understand their discomfort with his bluster, with his lack of any history supporting conservative ideas, with his many contributions to Democrat candidates, with some elements of his track record in business. Some of it bothers me too, although I do think a lot of the handwringing is over things that don’t really matter that much. But look, sure, nominating a guy like Donald Trump is in all kinds of ways contrary to what conservative movement types have advocated for...
