Iowa

Iowa conducts redistricting unlike any other state. The Iowa system does not put the task in the hands of a commission, but rather the legislature does vote on the plans. Nonpartisan legislative staff develop maps for the Iowa House and Senate as well as U.S. House districts without any political or election data including the addresses of incumbents. This is different from all other states.
