(CNN) - Joseph P. Kennedy III, the 29 year-old grandson of Robert Kennedy, has closed the door on a potential 2010 congressional bid, the latest member of the Kennedy family to forgo a bid for state-wide office.
Kennedy, whose father Joseph P. Kennedy II, was a six-term Congressman from Massachusetts, had been widely floated as a possible replacement to current Rep. Bill Delahunt, should Delahunt decide to retire.
Speaking to the Boston Globe, Kennedy, a recent Harvard Law School graduate, said he enjoys his current post as assistant district attorney covering the state's Cape Cod region.
"I think that we've got a great congressman. He continues to serve the people of the 10th District well," he said. "I'm a longtime supporter of his, and I hope he runs again."
But Kennedy is not ruling out a future run for Congress.
"Elective office and public service are obviously something that have long ties with my family, and something I'm definitely interested in. Right now, I've got a job I love, and hope to get better at," he said.
Kennedy's father considered, but ultimately ruled against, running late last year for the Senate seat that opened due to the death of late Sen. Ted Kennedy. That seat was ultimately captured by Republican Scott Brown.
Delahunt, 68, has yet to decide on whether he will mount a reelection bid.
