Attorney Chris Setaro has filed registration paperwork to run as a Democratic Mayoral candidate in Danbury.  The former City Councilman is looking for a 2001 rematch, challenging longtime Republican Mayor Mark Boughton, who beat Setaro by only 138 votes.  The election is still about 11 months away, but the Town Clerk's office was in receipt of the registration on Wednesday.  Boughton says he will be filing candidate paperwork, but after the budget process.  Setaro formed his own law practice in 2016 after working as an attorney for the Ventura Law firm for nearly 25 years. He served on the City Council from 1991 to 1998 and again from 2002 to 2003.
