Dan Rosenthal, one of the three selectmen of Newtown, Connecticut, is up for re-election in November 2021. Although he was first elected as a Democrat in 2019, this year he will instead run for re-election as the nominee of the SAM Party. See this story.
Newtown has a population of 27,560 and is somewhat famous for being the site of the 2012 Sandy Hook School shooting, which killed 26 people. It is in Fairfield County, which is in the southwest corner of the state.
The law for town officers provides that no party may run for more than two seats, even though all seats are up every two years.
