Joseph P. Kennedy III, who is considering a run for Congress, registered to vote in Brookline on Tuesday afternoon and listed a local address as his place of residence.
The 31-year-old, who is considering a run for the congressional seat being vacated by Barney Frank, registered as a Democrat in the town clerk’s office just after 4 p.m. Tuesday, according to Assistant Town Clerk Linda Golburgh.
The son of former US representative Joseph P. Kennedy II and the grandson of Robert F. Kennedy came into the town clerk’s office by himself and listed a Greenough Street address near Brookline High School, Golburgh said.
The address is just over a mile from the birthplace of his great-uncle, President John F. Kennedy, on Beals Street.
It is also located in the Fourth Congressional District.
Kennedy announced last month that he was exploring a run for that congressional seat, and he left his job as a prosecutor in Middlesex District Attorney Gerard T. Leone Jr.’s office.
Kennedy had been living in his mother’s house in Cambridge, but when he registered in Brookline, Golburgh said, he listed Hyannis as the last place he had registered to vote.
“Joe is taking some time to get across the district to listen to people’s thoughts on the issues facing families of the Fourth District as well as their thoughts on his potential candidacy,’’ Kyle Sullivan, a spokesman for Kennedy, said in an e-mail yesterday.
“Joe is thinking about running now precisely because of the difficult times we are in and the broken state of our politics in Washington,’’ Sullivan added. “There are critical issues facing the Fourth District right now, and Joe believes that we need to do more to create new jobs, provide better educational opportunities, and restore common sense and fairness in Congress.’’
Like Kennedy, Bristol District Attorney C. Samuel Sutter has formed an exploratory committee but hasn’t officially entered the race.
Democrat Herb Robinson of Newton is also running for the Fourth Congressional District seat, and another Brookline resident, Michael A. Burstein , a library trustee in the town, announced Wednesday that he has also formed an exploratory committee to run.
Republicans Sean Bielat of Norfolk and Elizabeth Childs of Brookline are also seeking the post.Globe correspondent Derek Anderson contributed to this report. Brock Parker can be reached at email@example.com.
Correction: Because of a reporting error, the original version of this article gave an incorrect congressional district for the seat being sought by Bristol County District Attorney C. Samuel Sutter. Sutter is running in the Ninth Congressional District.
