Jim Geraghty of National Review and Greg Corombos of Radio America are glad to see Republican leaders denounce the latest controversial comments from Iowa Rep. Steve King and argue that while it's worth defending the greatness of Western Civilization, there's a right way and a wrong way to do it.  While being perfectly fine with a wall at various points along our southern border, they offer multiple reasons why an emergency declaration to move it forward would be a bad idea now and an even worse precedent for when a Democrat eventually becomes president.  And they get a kick out of CNN's Jim Acosta intending to make an argument against the need for a border wall but accidentally demonstrating why a wall works.  And Jim explains how Acosta has become the Hollywood caricature of an arrogant reporter.
