Those who would be most directly affected show the least enthusiasm. Rep. Will Hurd, R-Texas, whose district includes 800 miles of the Mexican border, says “a wall from sea to shining sea is the most expensive and least effective way to do border security.” The Texas Border Coalition, made up of mayors and other officials from the area, calls it a “false promise.” For his Tuesday gala, Trump went to San Diego, whose City Council passed a resolution opposing the wall — which the Republican mayor declined to veto.
