History

Historical Context

The chaotic August 26-29 1968 Democratic National Convention in Chicago exposed deep party splits, prompting the McGovern-Fraser Commission to overhaul delegate selection. Its 1972 recommendations shifted the system from caucuses to primaries, ending an era when only 12 states used primaries. Maine’s current delegate contest, where Troy Jackson controls 290 of 319 seats, reflects that reform’s lasting impact.
