This would require some serious efforts to get candidates on the ballots of the various states for the general election. As far as I know nobody has actually done anything yet. Typical GOPe. They will just talk until it is too late to do anything about it. That is pretty much how the GOPe types handle everything.
This is just throwing a fishing line in the water and seeing if anything bites. Or nibbles.
It’s a smokescreen... the real plan is to steal the election at the convention.
