On October 21, Robert F. Kennedy, Jr. asked the U.S. Supreme Court to order the Wisconsin Election Commission to remove his name from the ballot. The State Supreme Court had kept him on against his will. Kennedy v Wisconsin Elections Commission, 24A399. Here is the filing. It is based on the argument that Wisconsin discriminates against independent candidates by letting party nominees withdraw, whereas independents can’t withdraw after the filing deadline unless they die. Thanks to Thomas Jones for this news.
The U.S. Supreme Court has set an October 28 deadline for a response.
