How do city council elections work?

The election for mayor and our 8 alderpersons happens on the first Tuesday each April. If there are more than 3 candidates for any one position, then a primary election is held on the third Tuesday of February; the top two vote-getters will then face each other in the April election.

Here in De Pere, where we have 8 alderpersons and a mayor, 4 alderpersons are up for election in the odd years, and the other 4 alderpersons along with the mayor are up for election on the even years.
