On May 20, U.S. District Court Judge Cindy Jorgenson upheld Tucson’s hybrid system of elections for city council. Members of each qualified party nominate a candidate for city council, in primaries conducted separately in each of the six wards. Then, in the general election, all the nominees from a particular ward run against each other citywide. The decision is 13 pages and says that the system does not discriminate for or against any voter. Public Integrity Alliance v City of Tucson, 4:15cv-138.
It is dubious that a city of 500,000 population should be holding at-large elections for city council.
