Zupnick co-founded a new advocacy group, Fix Our House, which argues that the only way to break America out of its political “doom loop where voters in each party see each other as enemies” is to change the way elections work — specifically, elections to the House of Representatives.

Zupnick founded the group along with two political scientists: Lee Drutman, a senior researcher at New America, and Charlotte Hill, a researcher with the Goldman School of Public Policy at the University of California, Berkeley. They’ve attracted support and board members from across the political spectrum, from lefties like Waleed Shahid of Justice Democrats to Never Trump Republicans like Miles Taylor of the Renew America Movement.

They believe proportional representation is the key to ending gerrymandering, breaking up congressional deadlock and reducing partisan divisions. The group argues that the nation is being driven to political extremes by an electoral system that might have worked before cable news, social media, super PACs and modern campaigning but now rewards those who promise to burn it all down.
