New Hampshire’s open U.S. Senate seat, created by incumbent Democrat Jeanne Shaheen’s retirement, has shaped trader views around the strong position of the likely Democratic nominee, Representative Chris Pappas. Recent polling from Saint Anselm College, the University of New Hampshire, and others shows Pappas ahead of Republican primary frontrunner John Sununu by margins ranging from roughly three to twelve points in head-to-head general election tests, with Scott Brown trailing further behind. These results, combined with the state’s underlying partisan lean and the September primary timeline, have produced the current market consensus that places the Democratic outcome well ahead of the Republican alternative.
