Meanwhile, the race in the state's Second District, which is yet another 2010 rematch, remains close. Democrat Ann McLane Kuster and GOP Rep. Charlie Bass are running neck-and-neck, with Kuster ahead, 38 percent to 35 percent. The size of the subsample in this race was also small -- just 211 likely voters -- and results carry a margin of error of plus-or-minus 6.7 percentage points. The percentage of undecideds in Bass's district increased, from 16 percent last month, to 25 percent now. The poll was conducted Oct. 1-6. The statewide sample consists of 419 likely voters.
