(CNN) - The field of Democratic candidates vying to replace the late Sen. Ted Kennedy appears to be growing.
Former Rep. Mike Capuano will officially get into the race Friday, his office has announced. Capuano, whose district represents parts of Boston and its immediate suburbs, is little known statewide, according to a new Suffolk University Poll.
Meanwhile, Stephen Pagliuca, the wealthy private equity investor and co-owner of the Boston Celtics, is reportedly also set to jump into the race on the Democratic side. Pagliuca has already lined up a staff and is willing to spend a considerable amount of his own $400 million fortune on the race, according to the Boston Globe.
The Democratic primary for the Senate nomination will take place December 8. The special election to fill the seat is scheduled for January 19, 2010.
