On April 6, North Dakota Governor Doug Burgum, a Republican, vetoed HB 1273. This is the bill that bans charter cities and town from using Approval Voting and also Ranked Choice Voting for elections for their own officers. Fargo, the largest city in the state, uses Approval Voting. No place currently uses Ranked Choice Voting.
On Friday, April 7, the House will consider whether to override the veto. See this story. Thanks to Daniel Ong for the link.
