Document 15: United States presidential primary: Delegates to the national convention were usually selected at state conventions whose own delegates were chosen by district conventions. Sometimes they were dominated by intrigue between political bosses who controlled delegates; the national convention was far from democratic or transparent. Progressive Era reformers looked to the primary election as a way to measure popular opinion of candidates, as opposed to the opinion of the bosses. Florida enacted the first presidential primary in 1901. The Wisconsin direct open primary of 1905 was the first to eliminate the caucus and mandate direct selection of national convention delegates. In 1910, Oregon became the first state to establish a presidential preference primary, which requires delegates to the National Convention to support the winner of the primary at the convention. By 1912, twelve states either selected delegates in primaries, used a preferential primary, or both. By 1920 there were 20 states with primaries, but some went back, and from 1936 to 1968, 12 states used them.
