Story summary

New Hampshire voters went to the polls on Tuesday for primaries that will determine the Senate candidate for the state's open seat, a crucial contest for Democrats' hopes of regaining control of the upper chamber. The seat became available when Jeanne Shaheen, the three-term incumbent Democratic senator from New Hampshire, announced her retirement. Congressman Chris Pappas, who represents New Hampshire's first district, is seeking the nomination and has a significant financial advantage with over $4m in cash on hand, but faces a challenge from Dr. Karishma Manzur, a scientist and progressive activist with no prior public office experience. If Pappas wins the primary, he will likely face John E. Sununu, a former senator endorsed by Donald Trump, who is seeking to return to the seat he previously held. The outcome of this contest has significant implications for Democrats' chances of regaining control of the Senate.
