The sharing economy is all the rage. People are sharing homes and cars, books and tools. Why not congressional districts?
Republicans and Democrats sink millions of dollars into a quartet of races that regularly flip from one party to the other. Over the last four election cycles, New Hampshire’s 1st District and Texas’ 23rd District have changed hands three times and New York’s 24th District has flipped all four. Illinois’ 10th District flipped back and forth in 2012 and 2014 and could do it again in 2016.
