A Bethel man has announced his candidacy for a state House seat.  Will Duff, past chairman of the Bethel Republican Town Committee, is seeking the GOP nomination in the 2nd District.  Incumbent Dan Carter announced this week that he will not be seeking reelection to the General Assembly, instead looking to take on Richard Blumenthal in the U-S Senate race.  Duff is a former Bethel Selectman and Board of Education member.  The 2nd District includes two thirds of Bethel, nearly two fifths of Redding, and small portions of Danbury and Newtown.
