In April 2012, Nicholas Fontana was appointed to the Arizona House of Representatives to represent the 29th district. He is the first independent state legislator since Arizona because a state in 1912 (except that his predecessor in that district had switched to being an independent but then had resigned a few days later).
Fontana is not running for re-election. The only candidates who will be on the ballot in the 29th district are two Democrats. Each Arizona state house district elects two members.
