Democrats haven't found a solid challenger to GOP Sen. Scott Brown in liberal Massachusetts next year. That's raising concerns the party could blow its best shot to take back the seat held for nearly a half-century by the late Sen. Edward Kennedy.
Brown stunned the political world by claiming the seat in 2010.
The senator's widow, Vicki Kennedy, has flatly ruled out running. So did former Rep. Joe Kennedy, nephew of the late senator. The state's leading Democrat, Gov. Deval Patrick, insists he's not interested. Former Rep. Martin Meehan has rejected pleas from party officials to jump in.
Democrats are facing a tough fight in 2012 to hang onto their slim majority in the Senate and a divisive primary could make a Massachusetts win even harder.
