Banning candidates from appearing on the ballot is what you do right before a civil war starts.
Seriously. This happened in 1860 when 10 Southern states wouldn’t put Lincoln on the ballot.
Unlike every preceding president-elect, Lincoln did not carry even one slave state, and indeed he was not on the ballot in 10 of the southern states: Alabama,Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina,Tennessee, and Texas.
