The open 5th Congressional District field of candidates could become as crowded as the gubernatorial race.  Elizabeth Esty announced Monday that she would not seek a 4th term amid questions about her handling of a sexual harassment case in her office. 

Her 2014 GOP challenger, Mark Greenberg, reportedly is switching from the state Comptroller race while the Republican party already has one declared candidate, former Meriden Mayor Manny Santos.  

One potential Democratic candidate has expressed interest.  Mary Glassman is the former first selectman of Simsbury and two-time lieutenant governor candidate.  Torrington state Representative Michelle Cook is weighing a run.  The party nominating conventions are next month.
