Republicans were hoping to flip this New Hampshire Senate seat – will Trump get in the way?

What happened: Democrat Chris Pappas and Republican John Sununu are contesting New Hampshire's open Senate seat to replace retiring Democrat Jeanne Shaheen, with Pappas tying Sununu to Trump in his closing message. Key numbers: Trump's approval in the state is 32% in a recent University of New Hampshire poll. Why it matters: Democrats cannot afford to lose a seat they hold as they seek four seats to reclaim the Senate, and a Republican strategist said low presidential numbers make it difficult to argue a Republican should win the seat.
