In pictures so even pspr can understand it ...or not http://motherjones.com/politics/2011/02/income-inequality-in-america-chart-graph
This is an interesting chart. Seven of the ten richest congressmen are Democrats. I guess they don't mind redistributing wealth - so long as it's someone else.
A more interesting question than how many are Democrats and how many are Republicans is: How many earned their wealth vs. how many married their money or inherited it?
Please note that the wealthy dems were in favor of increasing their own taxes...where the wealthy republicans were not...
