Rich and poor Republicans are more in agreement on social issues than they are on economic issues; meanwhile, rich and poor Democrats are in absolute agreement on economic issues but rich Democrats are more liberal than poor Democrats on social issues. For each quintile (1 = poor; 5 = rich), the average ideology is plotted with a normally-distributed confidence interval surrounding it. The x-axis represents the percentage of issues that the respondent took a conservative stance, ranging from 0% to 80% of the issues.
