Kent, Ohio, uses partisan city elections. At the November 3, 2009 election for Mayor, independent candidate Jerry Fiala and Democratic nominee Rick Hawksley ended up in a tie. On November 20, the election was resolved with a toss of a coin. See this story.
The curious part is that State law requires a recount, but the election board was required to determine a winner. The recount is to be completed by November 30.
