With 98 percent of precincts reporting, Hassan has a slender margin of just 640 votes over Ayotte at time of writing, out of more than 700,000 votes cast in the race. With the margin so tight, it's likely this election will undergo a recount process; if Hassan indeed wins the race, Democrats will have netted just two seats in the Senate this year, for an overall Republican majority of 52 seats against 48 for the Democrats.
