Provides an invaluable resource for scholars, students, and political observers who want a comprehensive picture of the past and present of the U.S. presidential nominating system across every state.

In 2020, the parties will again nominate their candidates for president. Those nominations will play out in a complicated system of federal law, state law, national party rules, state party rules, and informal norms that have developed over decades. This resource provides a roadmap for understanding the rules of the game and the ways in which they impact elections and politics across the United States.
