I suggest you vote for a freeper, Tom Hoefling, aka Eternal Vigilance.
I have been saying I would write in Sarah or some other social conservative republican, straight republican ticket up & down. So I’m vacillating on voting for Tom, but it won’t be that difficult to make a decision by November.
If the candidate has not signed and filed the appropriate forms, and provided a slate of electors, and met all of the other requirements, write in votes for them are not counted in most of the states.
Personally, I don’t believe in voting for folks who haven’t agreed to serve if elected, unless there is absolutely no acceptable choice available. Then it hardly matters.
