CONCORD, NH – The race to succeed retiring Democratic Senator Jeanne Shaheen in New Hampshire remains too close to call, with Maura Sullivan holding a slight lead over rival Stefany Shaheen in a tightly watched Democratic primary.

The outcome of Tuesday's contest will determine which candidate advances to face the Republican nominee in the general election for the open Senate seat, a race that could impact the balance of power in Washington.

Sullivan, daughter of the outgoing senator, has garnered a slim majority of the votes counted so far, according to preliminary results. Shaheen, a former state representative, has mounted a strong challenge, highlighting her own policy credentials and experience.

Both candidates have emphasized continuity with Senator Shaheen's legacy while also presenting their distinct visions for the Granite State. The close nature of the race underscores the competitive landscape within the state's Democratic Party as it seeks to hold onto a key Senate seat.

The primary has been closely monitored by national party strategists, as New Hampshire is considered a crucial swing state. The winner will likely face a challenging general election campaign in a state known for its independent streak and pivotal role in presidential politics.

Senator Shaheen, who has served in the Senate since 2009 and previously as New Hampshire's governor, announced her retirement earlier this year, creating the opening that has drawn significant attention from within the party.

As vote tabulation continues, both campaigns are preparing for the possibility of a protracted period of uncertainty. The final results are expected to be certified by state election officials in the coming days.

This race is one of several key primaries across the country as parties finalize their slates for the November general elections, with control of the Senate hanging in the balance.
