Americans Divided by Party and Ideology

ISI asked respondents two questions to determine their political orientation: Are you a Democrat, Independent, Republican, or something else? Are you liberal, moderate, or conservative? A respondent’s combined answer was then assigned an appropriate relative position on a scale of 1 through 5, with self-identified Democrat liberals placed at 5 and Republican conservatives placed at 1. Between these poles, Democrat moderates and Independent liberals were placed at 4 (left-leaning moderates); Democrat conservatives, Independent moderates, and Republican liberals were placed at 3 (Independent moderates); and Republican moderates and Independent conservatives were placed at 2 (right-leaning moderates).

The average American political orientation score was a 2.92 on this scale, just slightly to the right of political center.*
