Attorney Joseph Kennedy III (D), the son of former Rep. Joseph Kennedy (D-Mass.), raised more than $1.3 million in the first quarter in his bid for the Bay State’s 4th district seat.

“The donations came from more than 1,500 individuals; nearly half of whom gave $100 or less,” he wrote. “Not only will this money go a long way in ensuring we have the resources we need in the fall, but it is a fantastic show of the kind of on-the-ground support this campaign is built on.”

Kennedy, the presumptive Democratic nominee for the seat, will face either 2010 GOP nominee Sean Bielat or psychiatrist Elizabeth Childs in November for the seat currently held by retiring Rep. Barney Frank (D).

Roll Call rates the race as Safe Democratic.
