Greg Warrington, University of Vermont (IMAGE) University of Vermont Caption University of Vermont mathematician, Greg Warrington, has developed a new tool to help ferret out gerrymandered districts. "It's called the declination," he says. "Because there is no single standard of what exactly gerrymandering is, there is no one way to test for it.
