 J.D. Vance was introduced on the floor of the Republican National Convention yesterday afternoon. He came down to the strain of Merle Haggard's America First, which I think was a signal because J.D. Vance is famously rather isolationist when it comes to his foreign policy, certainly with regard to Ukraine. America First was actually a sort of isolationist ballad that was written in 2005 to rebuke the Bush administration. So the fact that J.D. Vance entered to the strains of that is somewhat telling. Here is what it sounded like.
