Other family members seen as possible heirs include his nephew, former Representative
Joseph P. Kennedy II. But despite his $2 million in leftover campaign funds, Joseph Kennedy has expressed reluctance to return to politics. Senator Kennedy’s sons, Edward M. Kennedy Jr. and Representative
Patrick J. Kennedy of Rhode Island, have also been mentioned.
Outside the family, there is a stable of high-profile Massachusetts Democrats considered possible successors, from Representative
Barney Frank, chairman of the Financial Services Committee; state Attorney General Martha Coakley and former Representative Martin Meehan, who retired to become chancellor of the
University of Massachusetts-Lowell last year, but who has about $4.8 million in campaign cash left.
