Democratic Rep. Chris Pappas is projected to win New Hampshire’s Democratic Senate primary on Tuesday, setting up what could be a tighter-than-expected showdown with Republican nominee John Sununu, a former senator.Pappas, a moderate who has run a campaign focused on combating government corruption, defeated Karishma Manzur, a medical scientist who ran as a staunch progressive and criticized Pappas’ opposition to Medicare for All, support for military aid to Israel, and other issues.Sununu defeated former Sen. Scott Brown, who tried to portray himself as more loyal to President Donald Trump even though the president had endorsed Sununu. Both candidates were winning by healthy margins as of 9:30 p.m. Eastern on election night: With roughly 44% of the votes in the Democratic primary reported, Pappas led Manzur 63% to 35%. Sununu led Brown 69% to 26% with just 32% of the votes in the GOP primary counted. Pappas, a 46-year-old four-term congressman, was seen as a heavy favorite, outraising Manzur by massive margins and attracting unanimous establishment support, but some late public surveys of the race had suggested Manzur had momentum in the closing days of the contest.With President Donald Trump’s approval rating at all-time lows, Pappas’ victory in a blue-tinted state like New Hampshire has long been seen as a relatively easy part of Democrats’ still-uphill battle for control of the Senate. But recent polls suggest a toss-up race, with Republicans spending more than $8 million attacking Pappas and little response from Democratic outside groups.That’s caused consternation among in-state Democrats, who fear the national party is underestimating Sununu’s appeal, given his popular name in-state and his association with his younger brother Chris, the state’s former governor.Republicans have made clear they plan to attack Pappas, who is the first openly gay person to represent New Hampshire in Congress, over his husband’s career as a lobbyist and policy executive for tech companies.“From now until November, SLF will spend every day highlighting John E. Sununu’s positive vision for New Hampshire while exposing the corruption, self-dealing, and radical record of Washington insider Chris Pappas,” said Alex Latcham, the executive director of Senate Leadership Fund, a super PAC controlled by allies of Senate Majority Leader John Thune.National Democrats, who feel more bullish about the race than their state-level counterparts, suggested they would work aggressively to link Sununu to Trump and would highlight his post-Senate career as a lobbyist. “He wants to go back to Washington to sell out New Hampshire to Donald Trump,” Senate Minority Leader Chuck Schumer and Democratic Senatorial Campaign Committee Chair Kirsten Gillibrand said of Sununu in a statement. “Granite Staters have a clear choice, and in November, they will send Chris Pappas to the Senate.”
