Two lower courts had already rejected the legal challenge by Democrat Josh Kaul, who argues that Musk's offer violates a state law.

Summary

Elon Musk handed $1 million checks to two Wisconsin voters at a Sunday rally supporting conservative court candidate Brad Schimel ahead of the state’s pivotal Supreme Court election.

But the state Supreme Court, which is currently controlled 4-3 by liberal justices, declined to take the case as an original action and gave no rationale for its decision.

Democratic Attorney General Josh Kaul argued the payments violated election law.

Musk’s groups have spent over $20 million in the race, which has drawn more than $81 million in total spending.
