There's a third Democrat entering the race for Danbury Mayor.  City Councilman John Esposito III has announced his intention to seek the party's nomination this summer.  The 36-year-old was born and raised in Danbury and has been on the Council since 2015.  Esposito says he would focus on improving the city’s infrastructure, recovering from the economic fallout of the pandemic, and addressing overcrowding and underfunding in the school system.  The plumber with Carmine’s Plumbing, Heating & Air Conditioning is married with two young children.  He is the grandson of Danbury's longest-serving member of the Common Council.  Republican Mayor Joe Cavo has not announced if he plans to seek a term of his own.  Democratic City Councilman Roberto Alves and Democrat Sedeaka Lawrence are in the running.  There hasn’t been a Democratic primary for mayor in Danbury since the 2001.
