As expected, Edward Flynn, son of the former mayor, is taking steps to run for the District 2 City Council seat that Bill Linehan is giving up.
Flynn, a South Boston resident, filed campaign organization papers with the state Office of Campaign and Political Finance on Feb. 17, two days after Linehan said he would not seek re-election for the seat, which covers South Boston, the South End, Chinatown, downtown and Bay Village.
Michael Sean Kelley, from Bay Village, meanwhile, filed his papers with the state the day before.
Last week, Corey Dinopoulos, from South Boston, registered his campaign with the state.
They join Frank Ulip, who lives downtown, and Peter Lin-Marcus of Chinatown as potential candidates for the two-year term.
Registering with the state does not mean a potential candidate will be on the September preliminary ballot - the city does not release formal petitions for city-council races until May.
