LOWELL — It’s two different stories for two big, bitter races in New Hampshire as voters prepare to cast their votes on Nov. 8.

Hillary Clinton is leading by six percentage points over Donald Trump in the swing state, according to a UMass Lowell/7News poll released Thursday. But in the race for U.S. Senate, only one percentage point separates incumbent Republican Sen. Kelly Ayotte and her challenger, Democratic Gov. Maggie Hassan.

Ayotte has the support of 45 percent of voters and 44 percent support Hassan. Only 6 percent of voters are undecided in this race.

“Incumbents tend to have a built-in advantage, but you also have a well-known opponent,” said Joshua Dyck, co-director of UMass Lowell’s Center for Public Opinion. “This is a very competitive race.”

Dyck said while Ayotte is trying to distance herself from Trump, she can’t do so to the extent that she loses potential votes from Trump supporters. Dyck said Senate races are typically more closely tied to the presidential race.

“In the next three weeks, if Trump’s numbers go up or down, that’s definitely going to have an impact on Kelly Ayotte,” Dyck said.

The outcome in this race will also determine whether Democrats will control the Senate.

Both presidential candidates are not particularly well liked among many voters, but only 4 percent of voters polled said they are undecided. Clinton has the support of 45 percent of likely voters, while 39 percent of voters polled said they would vote for Trump.

“I think that this is in line with expectations,” Dyck said. “At the national level, we’ve seen Hillary Clinton’s poll lead grow slightly since last Friday.”

The poll was conducted from Oct. 7 through Oct. 11, just after a video of Trump’s controversial conversation with Billy Bush was made public. However, just 7 percent of Republicans surveyed said hearing Trump’s lewd comments about women makes them less likely to vote for him.

“I think that game-changing moments are far more rare than we think and often have smaller effects,” Dyck said.

Although Republican voters may find things not to like in Trump and Democrats dislike things about Clinton, Dyck said that does not make them undecided voters, because most have one partisan leaning.

The poll also found that Gary Johnson, the Libertarian candidate, had the support of 11 percent of Republican voters in New Hampshire and 2 percent of Democrats.

What keeps Clinton in the lead, according to the poll, is not her honesty or trustworthiness. Only 33 percent of voters in the state said Clinton and Trump were honest and trustworthy candidates. But 61 percent of voters said Clinton is qualified for the position, while 34 percent said Trump was qualified.

In addition, 64 percent said Clinton had the temperament required to be president, while only 28 percent said that of Trump. Eighty-five percent of voters supporting Clinton and 79 percent of voters supporting Trump said they will not change their minds before Election Day.

Like the Senate race, the race for governor is a close one. Forty-one percent of voters support Republican Chris Sununu and 39 percent support Democrat Colin Van Ostern. With 14 percent of voters undecided on who to choose for governor, this race is even harder to predict.

A sample of 654 New Hampshire registered voters and subset of 517 likely voters were interviewed over the phone for this UMass Lowell/7News poll. The margin of error in the poll for registered voters is plus or minus 4.3 percent and for likely voters it is plus or minus 4.8 percent.
