John Tyler
Tyler started in government as a member of the Democratic Party, but later he changed to the Whig Party, which was very new. He was chosen to run as vice president next to William Henry Harrison. Whig Party people used to say "Tippecanoe and Tyler Too" to get people to vote for them. (William Henry Harrison was famous for being a general in a battle in a place called Tippecanoe, and that was his nickname.)
