Mexico’s president shoved back hard. ‘NO. Mexico will NEVER pay for a wall. Not now, not ever,’ Enrique Peña Nieto tweeted. ‘Sincerely, Mexico (all of us).’ But Trump earned some of his loudest applause at the Nashville Civic auditorium by declaring that despite high-wire-act negotiations over the North America Free Trade Agreement, he will find a way to soak America’s neighbors to the south. As the auditorium filled up and rally-goers shook the rain off their jackets and ponchos, country music star Trace Adkins performed – and included in his brief set list a tune called ‘Ladies Love Country Boys,’ which he said Trump had told him was his daughter Ivanka’s favorite song. The crowd went wild.
