Jake Grumbach's book "Laboratories against Democracy: How National Parties Transformed State Politics" is out now from Princeton University Press. We were lucky enough to receive and advance copy and are rebroadcasting our conversation with him from earlier this year.As many liberals were saying "thank God for federalism" in the Trump era, Grumbach saw some different — and disturbing — patterns emerging. He argues that as Congress has become more gridlocked, national partisan and activist groups have shifted their sights to the state level, nationalizing state politics in the process and transforming state governments into the engines of American policymaking in areas from health care to climate change. He also traces how national groups are using state governmental authority to suppress the vote, gerrymander districts, and erode the very foundations of democracy itself.Grumbach is an assistant professor of political science at the University of Washington. Additional InformationLaboratories Against Democracy: How National Parties Transformed State PoliticsGrumbach's websiteGrumbach on Twitter
