Americans have long used political draft movements to encourage non-traditional candidates to run.
In the 1952 election, future president Dwight D. Eisenhower only decided to run after his supporters registered him for the Republican New Hampshire primary.
In 1964, future Republican Presidential Nominee Barry Goldwater also entered the race in large part due to a political draft effort.
In 1992, Ross Perot decided to run only after a political draft effort took place. Perot would go on to win the largest share of the popular vote of any third-party candidate since Theodore Roosevelt.
All in all, American history suggests political drafts are an effective way for Americans to help prospective candidates make a decision to run.
