A new poll of the New Hampshire Senate race from Suffolk University finds Republican challenger Scott Brown within three points of Democratic incumbent Jeanne Shaheen. According to the poll of likely voters, Shaheen has 49 percent support to Brown’s 46 percent support. Shaheen’s job approval/disapproval rating is an even split at 46 percent. Brown’s favorable and unfavorbale ratings are 39 percent and 48 percent, respectively.

The poll shows a big bump in support for Brown, who in Suffolk’s poll in June had just 39 percent support. Shaheen’s support remains the same from that June poll, 49 percent. Overall, Shaheen has a 2.5-point lead in the Real Clear Politics average of polls. The race remains a toss-up.
