Is this in all of TN, or just one county where the Bushes might be gods in the local establishment?
Not sure.
The warning involves checking your ballot after voting. Make sure it says correctly who you voted for, and if wrong make a stink about it so THAT ballot is voided. Vote again, and again make sure the correct name is on your ballot.
I have read, in elections past, that sometimes you have to do the above more than once. Computers do what they are programmed to do, and in the above, that is cheat.
