The Democratic-controlled House is now an unusual combination of the richest and poorest districts, the best and least educated, and the best and the worst insured. The analysis found that Democrats have attracted educated, affluent whites who had tended previously to vote Republican. Democrats now represent 57% of the 4.8 million households that had incomes of $200,000 or more in 2008. In 2005, Republicans represented 55% of those affluent households.
