Not only do Democratic billionaires spend more on campaigns then Republicans do, as Katie Pavlich noted yesterday, but Democrats also represent the nation's richest congressional districts, while Republicans represent the middle class.

According to 2012 U.S. Census data, Democrats represent seven of the nation's ten richest congressional districts including, California 18 (median household income $100,917), California 17 (median household income $100,652), Virginia 11 (median household income $98,815), New York 3 (median household income $96,626), Virginia 8 (median household income $92,918), California 33 (median household income $92,111), and Maryland 8 (median household income).

Meanwhile, Democrats also represent nine of the nation's ten poorest congressional districts, including New York 15 (median household income $23,314), Mississippi 2 (median household income $29,981), Michigan 13 (median household income $30,273), Alabama 7 (median household income $31,080), Florida 5 (median household income $31,116), Ohio 11 (median household income $31,331), Arizona 7 (median household income $32,259), North Carolina 1 (median household income $32,488) , and California 34 (median household income $32,714).

And not only is the Democratic Party sharply divided between those that represent rich and poor congressional districts, but income inequality within Democratic congressional districts is far greater than it is within Republican ones. Of the top ten congressional districts with the highest levels of income inequality, Democrats represent nine of them.

The policy preferences of the Democratic Party reflect their top bottom divide. Just look at the cause of the last recession: housing.

Citibank, who was Hillary Clinton's biggest donor while she was in the Senate, made billions on subprime loans to poor households in the run up to the recession, then received billions in taxpayer bailouts when those loans went bad.

Now that Citibank has paid off the Obama administration, Obama is again pushing banks to make subprime mortgages to poor households again.

The rich Democrats on Wall Street get richer, Democrats can tell their poor constants they are "doing something" to make housing cheaper, and middle class American taxpayers get stuck with the bill.
