The Democratic lawmaker will face Bolduc in a live debate on Thursday organized by local news outlets including New Hampshire Public Radio (NHPR).

The Senate race in New Hampshire has received less attention than contests such as Pennsylvania and Georgia, but the latest Emerson College Polling/WHDH 7 News survey might cause concern among Democrats.

The Emerson poll found Hassan led Bolduc by just 3 percentage points, by 48 percent to 45 percent. A month ago, the same survey gave Hassan an 11-point lead.

Another poll, conducted on October 23 by InsiderAdvantage, showed that Hassan led Bolduc, a retired U.S. Army brigadier-general, by a single point—48 percent to the Republican’s 47 percent.

However, analysis from poll tracker FiveThirtyEight shows that Hassan is still favored to win. It gives her a 78 percent chance of victory, compared to 22 percent for Bolduc.

This gap has narrowed over the past month too. On September 27, FiveThirtyEight gave Hassan an 86 percent chance and Bolduc 14 percent.

Last week the Bolduc team pointed to a poll by Fabrizio, Lee & Associates, conducted for the Republican campaign from October 17 to 19, that placed him on 47 percent, just 2 points behind Hassan on 49 percent.

“Washington, D.C. may not be focused on this race, but the people of New Hampshire are sure paying attention, and that’s bad news for Senator Hassan,” the Bolduc campaign said in a statement on October 21.

A Republican victory in New Hampshire would be a significant upset and could decide the balance of power in the Senate, given the close races in Pennsylvania, Georgia, Arizona and Nevada.

It remains to be seen how the candidates will perform in Thursday’s debate. It will take place from noon to 1 p.m. local time and air live on NHPR. It will also be livestreamed online. The debate will be rebroadcast at 8 p.m. on radio and New Hampshire PBS.

Bolduc has focused on inflation and criticized Democratic policies that he says have exacerbated the problem. Hassan has taken aim at Bolduc’s previous comments on abortion that he would “always default for a system that protects lives from beginning to end.”

During the campaign, the Republican has said he believes the matter should be decided by the states and said he would vote against a federal abortion ban, while Hassan has described Bolduc’s earlier comments as “extreme.”

Newsweek has asked the Bolduc and Hassan campaigns for comment.
