Immediately after nominees were chosen in last month’s Republican and Democratic primaries, New Hampshire voters overwhelmingly said they had already decided which candidate they plan to pick in the general election for governor.

Republican incumbent Gov. Chris Sununu had backing from 55% of likely voters, putting him well ahead of his Democratic challenger, Dr. Tom Sherman, a state senator from Rye, who trailed with 37%, according to a UNH Survey Center poll conducted in the days after the Sept. 13 primary election.
