Okay so I am a day late with this one, but a century go the most successful third party campaign for the  Presidency was launched in Chicago. The 1912 Progressive Party ticket of Theodore Roosevelt and Hiram Johnson garnered over 27% of votes cast while receiving 88 electoral votes.  Political commentator John Avlon writes that many of the planks of the Progressive Party platform that TR championed are still topical today.

Avalon’s knowledge of the Presidency runs in the family. He is married to Margret Hoover, great granddaughter of Herbert Hoover.
