Some cities in America have a system of electing their councils by both, at-large and by district, which is better than entirely at-large. With an at-large system, basically, the same portion of the electorate elects the entire council, and thereby differences in ideology, if any, are nominal, and sectionalism, ironically, is more likely; it is a kind of reverse gerrymandering with the same outcome as gerrymandering. To change the system to "district only" or a "combination," a town citizen(s) would, generally, have to petition to get it on the ballot.
