"The Game Has Changed, and the Thing That's Changed Is Polarization"

"The splitting of American politics into two coherent ideological parties with very little programmatic overlap changes things. Voters who are fundamentally attached to one party or the other are not going to abandon their team merely because their party has held onto office for too many terms, or because the other party's president is presiding over a nice recovery. Those factors are not meaningless because some swing voters do still exist. And performance can change voter perceptions to a degree; a deep recession might make some Democrats doubt their party's economic program. But these temporal effects are muted.
"Emory political scientists Alan Abramowitz and Steven Webster have a new paper, not yet available online, exploring the nature of the new polarization. The paper is filled with interesting findings, but the major one is an attempt to resolve a paradox. Measured by self-identification, partisanship is actually declining—growing numbers of Americans describe themselves as 'independent' rather than loyal to one of the parties. But measured by actual voting behavior, the opposite is happening: Straight ticket voting continues to grow. This matches what operatives like Dan Pfeiffer have seen, and what Karl Rove saw a decade before—the swing voter had nearly vanished."


Jonathan Chait at New York looks forward to great partisan division in 2016.
