The deadline to get on the Utah primary ballot is Oct. 15
That is not what Utah says is the deadline:
Becoming a Federal Candidate
Office : President
Filing Dates : Between between July 1 of the year before the primary election will be held and 5 p.m. on January 15 of the year in which the primary election will be held

They are not interested in facts.
so is the earliest deadline 10/31 for all 50 states?
