On October 16, Colorado asked the U.S. Supreme Court to hear Colorado Department of State v Baca. This is the case in which the Tenth Circuit ruled that presidential electors have a right to vote for anyone for president who meets the constitutional qualifications.
Both such cases are now before the U.S. Supreme Court. The other one is from Washington state.
Here is Colorado’s cert petition. It argues that the electors didn’t have standing to file this case, and it also argues the merits of the case. The U.S. Supreme Court hasn’t assigned a case number yet. Thanks to Daniel Ong for this news.
