The open AZ-05 seat, vacated by incumbent Republican Andy Biggs' gubernatorial bid, drives trader consensus toward Republicans at over 80% implied probability in a district with R+10 Cook PVI and Biggs' prior 21-point 2024 margin. Trump-endorsed Mark Lamb leads the crowded GOP primary field per late-2025 polling and March fundraising reports showing strong cash reserves among Republicans like Daniel Keenan ($1.2M on hand), contrasting underfunded Democrats such as Chris James and Elizabeth Lee. No general election polls have emerged, but the partisan tilt and upcoming July 21 primaries reinforce structural barriers to a Democratic upset absent major shifts like scandals or national wave turnout.
