D. Mark McCoy, president of DePauw University (IN), writes: While most American colleges are said to tilt left, I am the president of a liberal arts college in a state that tilts right. I hear both sides regularly. In today’s echo chambers, that is an uncommon experience. Daily, I have the opportunity to learn from many sides. Our country was founded on such opportunities and the spirited debate they provoke. Such is the case with the Deferred Action for Childhood Arrivals (DACA), a program for young immigrants with an uncertain fate.
