The role of Musk — who is overseeing a controversial cost-cutting operation for Trump — made the race in part a referendum on him, said Barry Burden, director of the University of Wisconsin’s Elections Research Center.
“He is such an unusual person and he has this outsize influence in what is going on,” Burden said of Musk, who is listed by Forbes as the world’s richest person. “So that concern fit the narrative of what he was doing in the Wisconsin race, throwing his weight around and using his wealth. It was just a step too far for a lot of voters.”
