South Bend's mayor visited the [953 MNC](http://953MNC.com) studios Tuesday morning to talk at length about the daunting task that seems to lie ahead for him, and why he thinks it isn't too soon to make a run for The Oval Office. He also talks about his duties as mayor, his new book, the city's response to the Polar Vortex last week...and why he was on his way to physically help fill potholes after he spoke with Mark McGill.
