Minnesota election law requires qualified parties to file their presidential elector candidates, and an equal number of alternates, by August 29. The Republican Party has complied with this law. However, when it first nominated presidential elector candidates earlier this year, it forgot it was supposed to also nominate alternates. See this story.
When the party realized this, it called a meeting of the state committee, nominated alternates, and forwarded them to the Secretary of State by the legal deadline. However, the meeting that was called to choose alternates was in violation of the party bylaws, which say a 10-day notice is required for meetings. The party ignored that bylaw because of the time emergency. Thanks to Jeff Becker for the link.
