“The key idea here is “negative partisanship”: partisan behavior driven not by positive feelings toward the party you support but negative feelings toward the party you oppose. If you’ve ever voted in an election feeling a bit bleh about the candidate you backed, but fearful of the troglodyte or socialist running against her, you’ve been a negative partisan. It turns out a lot of us have been negative partisans. A 2016 Pew poll found that self-described independents who tended to vote for one party or the other were driven more by negative motivations. Majorities of both Republican- and Democratic-leaning independents said a major reason for their lean was the other party’s policies were bad for the country; by contrast, only a third of each group said they were driven by support for the policies of the party they were voting for.”
