The Town Committees in Danbury are meeting this week to formally endorse candidates for Mayor.  With Mark Boughton taking a job with the state and Joe Cavo opting not to seek a term of his own, there's an open race for the first time in about two decades to lead the City.  The Democratic Town Committee previously endorsed City Councilman Roberto Alves, but are meeting tonight to make the nomination.  The Republican Town Committee meets tomorrow and plan to nominate Dean Esposito, the mayor’s chief of staff.  Two other Democrats, Councilman John Esposito III and political newcomer Sedeka Lawrence, could force a primary in September. The two parties will nominate down ballot candidates as well, including Town Clerk, Treasurer and others.
