The Danbury Democratic Town Committee has formally nominated a candidate for Mayor.  With the election still nearly a year away, the group endorsed Chris Setaro.  The former City Council president is looking for a rematch of his narrow defeat in 2001 by Mark Boughton during the Republican's first run for the office.  Setaro has already taken in more than $25,000 in contributions since announcing his intentions last month. The Democrats also nominated someone to replace Tom Saadi on the City Council.  Saadi, who was renominated as state Veteran Affairs Commissioner last month, plans to formally resign tonight. Board of Education member Farley Santos, a banker of Brazilian descent, was nominated to the 4th Ward position.
