Sharing a chapter I have written for The Oxford Handbook of American Election Law (Eugene Mazo, ed.) (2023, forthcoming). The chapter, among other things, stresses the ways that the U.S. Supreme Court’s current approach to the associational freedom of political parties significantly constrains party reform strategies. Given the manifest need for party regulation in the interest of a healthy democracy and the recent buzz around Lee Drutman’s report and op ed arguing for more and better parties, this seems a good time to share.
