State Sen. John Cavanaugh leads Polymarket trader consensus at 67.5% to win Nebraska's 2nd Congressional District Democratic primary on May 12, bolstered by his incumbency advantage, local name recognition from prior legislative service, and campaign-commissioned GBAO polls showing him ahead by 21–28 points over unnamed rivals. Challenger Denise Powell holds 23.5% amid a surge from national groups—EMILYs List Women Vote, CHC BOLD PAC, and Elect Democratic Women—launching a $1 million TV ad program this week, plus a GQR message-test poll giving her a 41–34 edge after voter briefings. The April 12 KETV forum amplified attacks on Cavanaugh's potential state senate vacancy, which GOP Gov. Jim Pillen would fill, risking Democratic legislative control. Lower odds for Evangelos Argyrakis (4.2%) and Mark Johnston (3.5%) reflect his disbarment controversy and prior withdrawal, respectively, in this crowded field for the open seat.
