In Arizona’s nasty, hard-fought 2018 Senate race, it’s all going to come down to turnout

Out of 35 US Senate elections this year, Arizona’s is one of only three without an incumbent. Barbara Norrander and Lisa Sanchez write that the contest between US House Representatives Republican Martha McSally and Democrat Krysten Sinema is a close and hard fought one, with both going negative in their campaigns. While this negativity may energize both party’s respective bases, they argue that it may turn off independent voters – a group both candidates need if they want to head to Washington DC in January 2019.
