MADISON, Wis. (AP) — A group funded by billionaire Elon Musk is offering Wisconsin voters $100 to sign a petition in opposition to “activist judges,” a move that comes two weeks before the state’s Supreme Court election and after the political action committee made a similar proposal last year in battleground states.

Musk’s political action committee America PAC announced the petition in a post on X on Thursday night. It promises $100 for each Wisconsin voter who signs the petition and another $100 for each signer they refer.

The campaign for Susan Crawford, the Democratic-backed candidate for Wisconsin Supreme Court, said Musk was trying to buy votes ahead of the April 1 election. The offer was made two days after early voting started in the hotly contested race between Crawford and Brad Schimel, the preferred candidate of Musk and Republicans.

The winner of the election will determine whether the court remains under liberal control or flips to a conservative majority.
