Many Americans report that they are frustrated by the two-party system and wish the U.S. were more of a multiparty democracy.

Might the viability of more than two parties in legislative contests encourage more voter participation in presidential elections as well? Peter and Dale discuss the opportunities and challenges posed by third parties with political scientists Lee Drutman, Charlotte Hill, and Sandy Maisel.
