A Musk Lawsuit in Wisconsin Is the Backdrop to the State’s Supreme Court Race

I was driving from Eau Claire, Wis., to Minneapolis last week when I saw the sign.

A Tesla sign.

Soon after I crossed the St. Croix River, which divides Wisconsin and Minnesota, a brick-and-steel tower visible from Interstate 94 advertised the Tesla store and service center in Lake Elmo, Minn.

The dealership’s proximity to the state line is probably no accident: Wisconsin law prohibits vehicle manufacturers from selling cars directly to customers there, the way Tesla usually does. Instead, companies need to work through local franchisees — think Hank’s Ford or Jimmy’s Subaru, that sort of thing.

This means that, in Wisconsin, you can’t actually stroll into a dealership and leave with a Tesla. You can look at one — the company has showrooms in Madison and Milwaukee — but if you want one, you’ll generally have to buy it online and pick it up somewhere like Lake Elmo or Northern Illinois, or have it delivered.

Tesla sued Wisconsin over this law in January. Now, Tesla’s owner, Elon Musk, is spending big money on the state’s Supreme Court race.

The lawsuit has become a major focus for Democrats, who are accusing Musk of trying to buy a justice and swing the very court that might at some point consider his lawsuit. My colleagues Reid Epstein, who writes about national politics, and Neal Boudette, who covers the auto industry, teamed up to explore the relationship between the lawsuit and Musk’s $20 million investment — so far — in the judicial election, which will be held on April 1.

The politics of Tesla’s fight with Wisconsin are, like so much involving Musk, kind of topsy-turvy. It pits car dealers, who tend to be Republican, against Musk supporters, who these days also tend to be Republican.
