### Results

In the early months of the campaign, Hassan maintained a healthy lead in the polls. Polls began to tighten around September 2022 and by late October, a few polls even showed Bolduc with a narrow lead or had the candidates tied. Most pundits concurred that Hassan had a very slight edge and that the race would be extremely tight. However, Hassan won reelection by 9 points, a margin considerably wider than what was expected and one far greater than her 0.14 point plurality in 2016. Hassan's victory made her the first Democrat to win re-election to the class 3 Senate seat in New Hampshire history. This, along with Democrats' comfortable victories in New Hampshire's two House races, affirmed New Hampshire's transition from a closely contested swing state to a clearly Democratic leaning state at the federal level.
