On May 31, Paul S. Leon, Mayor of Ontario, California, changed his registration from “Republican” to “independent.” He has also filed for the special election to fill the vacant 52nd Assembly seat. That election will be on July 23. He will be facing eight other candidates, all of whom are Democrats or Republicans. See this story.
Leon ran in a special election earlier this year for State Senate, with the “Republican” label. He did not win.
