Of those presidents none has called for "zero tariffs, zero subsidies, zero non-tariff barriers". How excited would libertarians have been to hear a major party president so much as say this during the years 1976-2012?

Of course, I would prefer it if Trump, when he makes such statements, had the commanding presence of George Washington, the erudition of Thomas Jefferson, the charm of John Kennedy, the family life of Jimmy Carter, but he doesn't. Trump is who he is. (And I have to wonder if it just takes a personality like that of Trump to have accomplished the positives he has so far, against such overwhelming opposition.)
