New Hampshire Senate: Maggie Hassan 46, Kelly Ayotte 38

When undecided voters were asked who they were leaning toward supporting, Hassan leads Ayotte 48 percent to 39 percent, with 4 percent supporting someone else and 9 percent undecided.

The University of New Hampshire Survey Center polled 907 randomly selected New Hampshire adults, including 770 likely voters, from Oct. 11-17. The margin of error for the likely voter sample was plus or minus 3.5 percentage points.

The survey center said the new poll marked the first time either candidate in the Senate race “has held a statistically significant lead since the UNH Survey Center began polling on this race in May 2015.”
