Mandela Barnes, the former Wisconsin lieutenant governor who ran for U.S. Senate in 2022, has dropped out of the Democratic primary race for governor of Wisconsin. The withdrawal was announced July 30 and confirmed by multiple outlets on July 31, significantly altering the shape of the Democratic field ahead of the primary.

Barnes had been considered a prominent candidate given his statewide name recognition and his prior Senate run, in which he lost narrowly to Republican incumbent Ron Johnson. His decision to exit the race came as a surprise to many observers and Democratic insiders tracking the competitive primary.

With Barnes out, attention has shifted to the remaining candidates in the field. At least one candidate with ties to the Democratic Socialists of America is now viewed as a frontrunner, a development that has drawn scrutiny from both Democratic strategists and conservative commentators assessing the party's positioning in a key battleground state.

Wisconsin's governor's race is considered a high-stakes contest, as the state has been a perennial swing state in presidential and statewide elections. Democrats currently hold the governorship under Tony Evers, who has not announced whether he will seek another term, making the primary field particularly consequential for the party's prospects in 2026.
