**JoCasta Zamarripa holds an 81% implied probability in this open-seat race after incumbent Sarah Godlewski opted to run for lieutenant governor instead.** Wisconsin’s Democratic primary left Zamarripa unopposed, while Republican Jay Schroeder prevailed in a four-candidate field with roughly 47% of the vote. Sabato’s Crystal Ball moved the contest from toss-up to Leans Democratic in September, citing Zamarripa’s stronger fundraising and the party’s structural edge in recent statewide contests. The candidates differ sharply on the office’s scope: Zamarripa favors modest modernization and staffing increases under the current framework, whereas Schroeder centers his campaign on shifting election administration from the bipartisan Wisconsin Elections Commission to the secretary of state. With the November 3 general election three weeks away, trader pricing reflects these primary results, fundraising disparities, and the nonpartisan rating shift more than late-cycle polling.
