Connecticut AG Blumenthal to Run for Dodd's Senate Seat

HARTFORD, Conn. -- Connecticut Attorney General Richard Blumenthal says he decided to seek the U.S. Senate seat of fellow Democrat Chris Dodd to continue to fight against scams and special interests. 

Blumenthal announced his decision to run Wednesday at Democratic headquarters in Hartford, just hours after Dodd announced from his East Haddam home that he would not be seeking a sixth term in November. 

Dodd has been dogged by lagging poll numbers for months.

Blumenthal has been Connecticut's attorney general since 1990. He has gained a national profile by challenging Big Tobacco and its alleged marketing to children and the Web site Craigslist and its erotic ads that promote prostitution.
