It's still looking good for Elizabeth Warren's fundraising prowess. The Massachusetts Democrat aiming to oust Sen. Scott Brown (R-Mass.) raised $8.67 million in the past three months, her most successful quarter so far, the Warren campaign announced Monday. The race between Warren and the moderate conservative is close, with a recent Boston Globe poll finding only a two-percentage point margin favoring Brown.Warren far outraised Brown in the first quarter of 2012, bringing in $6.9 million to her opponent's $3.4 million.
