Van Buren is the only sane choice in this election.
To be fair John Tyler was apart of the Virginia Peace Conference which tried to find a peace agreement between the USA and the CSA. He opposed secession until the U.S. Congress rejected the agreement and only then decided that the U.S. government had no interest in peace. Additionally, as president Tyler was willing to send troops to Rhode Island to put down Dorr's Rebellion thus showing he was willing to attack "traitors." Not that I agree with that but still.
