After trailing by as much as twelve points earlier this summer, Scott Brown is now statistically tied in the New Hampshire Senate race against Democratic senator Jeanne Shaheen, according to a new poll.

A new WMUR Granite State Poll finds Brown, a former Massachusetts senator now running in the neighboring state, trailing the incumbent Shaheen 44 percent to 46 percent. The two-point difference falls within the margin error.

A June survey by the same group of pollsters showed Brown down twelve points to Shaheen. Two July polls conducted by CBS News/New York Times and NBC News/Marist also didn’t look promising for Brown: Shaheen held ten-point and eight-point leads, respectively.

Brown has recently gone on the offensive in the wake of the ongoing border crisis, hitting Shaheen for her stance on immigration and her support on the president’s policies. Brown is expected to prevail next month’s Republican primary, after which his campaign should gain further ground.
