Harvard Law Professor Elizabeth Warren (D) raised a whopping $5.7 million in the fourth quarter of 2011, her campaign announced today.

Sen. Scott Brown (R) raised $3.2 million for the race against Warren in the past three months — a respectable total for a Senate candidate but one that pales in comparison to Warren’s haul.

“From all across our commonwealth, people are supporting our campaign and the fight to level the playing field for middle class families,” Warren said in a statement.

Warren, a former administration official, announced her campaign in September. She quickly tapped into a network of progressive activists who supported her creation of the Consumer Financial Protection Bureau.

She outraised Brown in the previous quarter as well, $3.15 million to $1.55 million.

"Elizabeth Warren is being financed by extreme liberal special interests from outside Massachusetts,” said Massachusetts Republican Party spokeswoman Alleigh Marré in a statement.

But Brown still has far more cash on hand than his rival — $12.8 million to Warren’s $6 million, according to the Boston Globe.

Brown and Warren are two of the top fundraisers of the 2012 cycle, gearing up for what is sure to be a very expensive, very competitive race. The most recent polling has Warren leading by 7 points.
