State Sen. John Cavanaugh leads Polymarket odds at 81% implied probability to win Nebraska's 2nd Congressional District Democratic primary on May 12, driven by his incumbency advantage, endorsements from the Congressional Progressive Caucus PAC, unions, and state senators, plus internal GBAO polls showing him ahead by 21–28 points over rivals. Recent Republican super PAC ads from the Congressional Leadership Fund—mailers and TV spots tying Cavanaugh to Trump-era tax exemptions on overtime and tips—aim to boost challengers like Denise Powell (11.5%), signaling GOP views him as the weakest general election foe against presumptive nominee Brinker Harding. Powell benefits from top fundraising exceeding $1 million through 2025, while Evangelos Argyrakis (4.5%) and withdrawn Mark Johnston (3.7%) lag due to controversies and dropout. Rivals highlight risks of Cavanaugh vacating his senate seat, potentially enabling GOP supermajority and redistricting threats to the district's split electoral vote. Early voting ballots begin mailing soon.
