Mitt Romney delivered the commencement address at Southern Virginia University this past weekend, his second public speech since he lost the 2012 presidential election. His speech was inspired by a story from Luke's gospel, when Jesus calls his first disciples, a group of lowly fishermen. "Launch out into the deep," he tells them, "and let down your nets." For Romney, "launch out into the deep" is a metaphor for life: He tells the graduates to be bold, selfless, unafraid of life's challenges. One way to embrace this philosophy, according to Romney, is to marry young . . .
