As far as I can tell, Donald Trump is an unprincipled vulgarian. He would make a big show of deporting illegal aliens, only to "let the good ones back in." He supports single-payer healthcare. Before he flipped on the issue, he wanted to admit tens of thousands of Syrian "refugees." He has very un-American strongman tendencies. Yet he's leading in the Republican primaries. So please help me understand: How would President Trump be better than, say, President Cruz?
