Rebecca Cooke maintains a commanding lead in the Wisconsin 3rd congressional district Democratic primary, driven by her prior statewide name recognition from narrow 2024 general election and 2022 primary runs, substantial fundraising edge over challenger Emily Berge, and endorsements from Sens. Tammy Baldwin and Bernie Sanders along with the Democratic Congressional Campaign Committee and local unions. The August 11 primary offers little runway for shifts, with Cooke positioned as the consensus choice among party infrastructure and major donors. Berge’s insurgent effort, focused on local priorities and rejecting corporate PAC funds, has not closed the gap in visibility or resources. Late developments such as unexpected polling swings, health issues, or major scandals could still alter the outcome before polls close.
