On March 7, Kansas State Senator John Doll said he is changing his registration from Republican to Independent. He represents southwest Kansas. He will be the Lieutenant Governor running mate for independent gubernatorial candidate Greg Orman. See this story. Doll has been in the legislature since 2012, and he was Mayor of Garden City before he was elected to the legislature.
The number of state legislators who have left the Democratic and Republican Parties in the last few years is probably higher now than at any time in the last one hundred years.
