In 2021, the Idaho legislature passed HB 231, which changed the petition deadline for independent presidential candidates from August 25 of the election year, to the tenth Friday before the primaries. Therefore the 2024 deadline is March 10.
This change violates the U.S. Supreme Court decision Anderson v Celebrezze, 460 US 780 (1983), which said early petition deadlines for independent presidential candidates are unconstitutional. Idaho is the third state to have passed a law recently that contradicts Anderson v Celebrezze. The others are Utah (which did so in 2022) and North Carolina (which did so in 2021).
BAN had not previously reported this Idaho development. Thanks to Paul Rossi for the news. It is likely that Robert F. Kennedy, Jr., will soon file a lawsuit against the Utah deadline. Utah already lost on this issue in 1984, when Lyndon LaRouche sued to overturn the then-April deadline. Utah then changed it to September, but in recent years forgot why it did that, and moved it to January.
