(Ariel Edwards-Levy | Huffington Post) -- Rep. Michele Bachmann (R-Minn.) is polling within the margin of error of Democratic challenger Jim Graves, according to an internal poll from the Graves campaign.
The poll, conducted by the Democratic firm Greenberg Quinlan Rosner and first reported Monday by Salon, showed 48 percent of likely voters supporting Bachmann and 46 percent backing Graves in the race for Minnesota's 6th district. A previous GQR poll in June had Bachmann ahead by 5 points, 48 to 43 percent.
