Not content with spending more than a quarter of a billion dollars to elect Donald Trump and Republican candidates in 2024 and then taking a wrecking ball to the federal government, Elon Musk is now trying to flip the balance of power on the top court in one of the country’s most important swing states.

Building America’s Future, a dark money group backed by Musk, is spending at least $1.6 million in support of Wisconsin Supreme Court candidate Brad Schimel, a conservative judge in suburban Milwaukee who is running for an open seat in an April election that will decide whether progressives or conservatives control the court. The group began running ads across the state on Thursday.
