The retirement of longtime Democratic incumbent Jeanne Shaheen has created an open-seat contest in New Hampshire, a state with a modest Democratic lean reflected in its partisan voting index. Democratic Representative Chris Pappas holds a commanding lead in the September 8 primary and general-election polling against likely Republican nominee John Sununu, contributing to the market's strong Democratic consensus. Polls from June through August show Pappas ahead or in a statistical tie in head-to-head matchups, while the Republican primary remains more fragmented between Sununu and former Senator Scott Brown. Trader pricing at 89.5% for a Democratic winner aligns with the state's recent voting patterns and the absence of major late-breaking shifts that would favor a Republican pickup in this cycle.
