On February 18, the Wyoming Senate passed HB 76. It had already passed the House. It says that if the Secretary of State has not received the certification of any qualified party as to whom it nominated for president and vice-president by 60 days before the November election, the state will not print the name of that party’s national nominees on the November ballot. Instead it will just say, for example, “Republican nominees for president and vice-president” without naming them.
Most states have deadlines but give the Secretary of State leeway on the actual date.
Surprisingly, about half the states don’t even have a law on the subject of when (or even whether) qualified parties should certify their presidential & v-p nominees. It seems to work OK that state elections officials read the newspapers and just know who got nominated.
