Do a write-in vote.
The Mississippi ballot has a space for a write that’s mandated by law but write in votes are not counted by law. The fact that you did will be noted and will be reflected as no vote for that office, more voters than votes cast. If a large number of people did it and especially if you used the same name it would make at least an impact on the rethuglians and give them someone to blame for thad’s loss. I plan on doing this and recruiting as many as I can to do the same.
