A woman who automatically qualified for the primary to be the Democratic 5th Congressional District nominee has won the backing of the Connecticut Working Families Party.  Jahana Hayes, a Waterbury teacher, barely missed being the Democratic nominee at the party's nominating convention.  She is challenging endorsed candidate Mary Glassman.  They are vying to replace incumbent Elizabeth Esty, who decided not to run for reelection amid a controversey over her handling of a sexual harassment case involving her former chief of staff. Republican-endorsed candidate Manny Santos is being challenged in an August 14th primary by Ruby Corby O’Neill of Southbury and Richard Dupont of Watertown.
