Alaska’s August 18 top-four nonpartisan primary features a crowded field of 17 candidates vying for four general-election spots in an open-seat race after term-limited Republican Governor Mike Dunleavy. Trader probabilities on leading contenders such as Dave Bronson, Click Bishop, and Treg Taylor reflect name recognition, recent polling margins, and early-voting patterns in a system where every vote can shift rankings. Polls from spring and summer show Democrat Tom Begich with the highest overall support, while Republicans Bronson and Bernadette Wilson lead their party’s share; however, the large field and low turnout create volatility. Heavy outside fundraising and campaign events in the final week have narrowed gaps among the top six, with outcomes hinging on how independents and crossover voters rank lesser-known candidates in the remaining hours before polls close.
