Readers have asked about my evidence for the proposition that conservatives are generally better informed about politics than are liberals. I was likely recalling the following chart, posted on the VC several months ago:

Political Knowledge by Strength of Party Identification
2000 National Election Study
Self-Described Party Alignment / Average Political Knowledge Score
(Average number of correct answers on 31 point scale)
"Strong Republican / 18.7
"Independent-Republican / 15.7
"Strong Democrat / 15.4
"Independent-Democrat / 14.2
"Weak Republican/ 14.1
"Weak Democrat / 13.3
"Independent-Independent / 9.5

If being a strong Democrat is highly correlated with being liberal, and being a strong Republican is highly correlated with being conservative, than based on this data, my statement was likely correct, though I am open to a contrary showing.
