Mary Peltola leads the Alaska Senate race at 62.5% in trader consensus, ahead of incumbent Republican Dan Sullivan at 38.5%, driven by her consistent polling edge and record fundraising since announcing her candidacy in January 2026. Recent Alaska Survey Research surveys from June show her ahead by roughly five points in head-to-head general election matchups, building on earlier results that placed her near or above 48%. The state’s nonpartisan top-four primary on August 18, followed by ranked-choice voting in the general, amplifies her profile as the most recent Democrat to win statewide office. Traders also factor in potential voter confusion from a second Republican named Dan Sullivan on the primary ballot, a development highlighted in early June reporting that could fragment support. Sullivan retains the advantages of incumbency and a Trump endorsement in a Republican-leaning state, yet faces a tighter contest than historical patterns suggest.
