On May 19, the U.S. Supreme Court refused to hear Lindsey v Whitmer, 24-1017. Eleven Republican state legislators in Michigan had brought the lawsuit, alleging that it violates the U.S. Constitution when voters use the initiative process to alter election laws that affect federal elections.
The theory that only state legislatures and Congress can change election laws that affect federal elections now seems virtually dead. The initiative process has been used in Massachusetts and Florida to improve ballot access laws, and it will probably be used in the future for that same purpose.
