@markzbarabak The 1968 Democratic convention, where one-quarter of the delegates were chosen in back-room caucuses in 1967, transformed how we nominate presidents. In 1968, there were 3 binding primaries (not beauty contests). In 1980, 33 such primaries. Kudos on these facts to @EKamarck. — PolitiTweet.org
