Democratic U.S. Rep. Chris Pappas will face off in November against Republican former Sen. John E. Sununu to be U.S. senator, after the two candidates prevailed in their respective primaries Tuesday. The results, projected by the Associated Press shortly after 8 p.m., solidified what will likely be a bare-knuckled, expensive general election fight for the Senate seat, which is open after Sen. Jeanne Shaheen announced her retirement. Polls suggest the contest between Pappas, the current representative for the 1st Congressional District, and Sununu could be close, and both candidates had been positioning themselves for the general election months before the primary. As the polling has tightened, the race has taken on increasing significance to Democrats’ chances to flip control of the U.S. Senate, with Pappas’s shrinking advantage drawing national attention. In winning his primary, Sununu held off a challenge from Scott Brown, the former U.S. senator from Massachusetts who has since moved to New Hampshire, after Brown attempted to align himself with President Donald Trump and run to Sununu’s right.
