All the states have different rules for getting on the ballot (I think there’s one (Ohio?) where the deadline is before the convention). Don’t assume good faith on the part of any republican officials
Correct. Aware. This is why the DNC is roll calling early — before the convention, before the deadlines — to officially nominate Biden. They can do the same for Harris after Biden drops out.
No issue at all, except there’s not much time to waste.
