On this day four years ago, Maryland Democratic U.S. Representative John Delaney was already 205 days deep into his 2020 presidential campaign – by far the earliest campaign launch by a bona fide major party candidate during the primary era. Delaney announced his campaign on July 28, 2017 – some 1,194 days prior to the 2020 general election. He exited the race on January 30, 2020 after 2 years, 6 months, and 3 days on the campaign trail.
