Americans are more than twice as likely to identify themselves as conservative rather than liberal on economic issues, 46% to 20%. The gap is narrower on social issues, but conservatives still outnumber liberals, 38% to 28%.
[. . .]
These results are based on Gallup's annual Values and Beliefs poll, conducted May 3-6. Since 2001, the poll has asked Americans to say whether they are liberal, moderate, or conservative on "economic" and, separately, "social" issues. The interpretation of what qualifies as social or economic issues is left to the respondent, given that the question does not define or provide examples of these types of issues.
Note that in both the economic and social-issue categories, there are 34 percent who commit to neither side. It's that third that's undoubedly screwing things up.
