Joseph P Kennedy III aims to resurrect famous political dynasty Mr Kennedy, a 31-year-old Massachusetts prosecutor, is in the final stages of preparing a Congressional run, with hopes to succeed Barney Frank, the retiring Democratic Representative, according to the Boston Globe and Rhode Island Public Radio. The committee is an important legal step that would allow him to start raising campaign funds, as well as preparing to quit his job at the district attorney's office. "My decision to look seriously at elected office is grounded in a deep commitment to public service and my experience - both my own and that of my family - in finding just, practical, and bipartisan solutions to difficult challenges," Mr Kennedy said in the statement. One or more members of the storied and troubled US political clan have served in Washington since John F. Kennedy successfully ran for a House seat from Massachusetts in 1946, before going on to win the presidency. The death in 2009 of Senator Edward Kennedy was seen as a landmark, leaving no Kennedys in high political office and ending the last high-profile public link to the era of the assassinated JFK. The Kennedys were once an unbeatable political brand in liberal Massachusetts, but their decline came into relief when a special election to fill Edward Kennedy's vacated Senate seat was won by Republican Scott Brown.
