Today’s parties are hollow parties, neither organizationally robust beyond their roles raising money nor meaningfully felt as a real, tangible presence in the lives of voters or in the work of engaged activists. The parties have become tarred with elements of polarization that the public most dislikes—from the screaming antagonism to the grubby money chase. More than any positive affinity or party spirit, fear and loathing of the other side fuels parties and structures politics for most voters. Party identification drives American politics—but party loyalty, in the older sense of the term, has atrophied. Even the activists who do so much to shape modern politics typically labor outside of the parties, drawn to ideologically tinged “para-party” groups such as MoveOn.org on the left or the Koch-backed Americans for Prosperity on the right. The parties offer clear choices but get no credit. Our new Party Period features a nationalized clash of ideology and interests but parties that are weakly legitimized and hollowed out.
