The polls were commissioned by liberal PAC the Progressive Change Campaign Committee and conducted by Democratic polling firm Public Policy Polling on Sept. 24 and 25.
In New Hampshire's 1st district, Shea-Porter pulls 48 percent support to Guinta's 47 percent support, with 4 percent undecided. That's similar to the last independent poll of the district, taken in August, which gave Shea-Porter a two-percentage-point lead.
In New Hampshire's 2nd district, Kuster has 51 percent support to Bass' 46 percent support, with 4 percent undecided. That's the exact opposite of what the last independent poll, taken in August, revealed about the district -- it put Bass up by five percentage points.
The 1st district poll was conducted among 401 likely voters and has a margin of error of plus or minus 4.9 percentage points, and the 2nd district poll was conducted among 461 likely voters and has a margin of error of 4.6 percentage points.
The Hill rates both of these races as tossups.
