While I doubt the disparity in numbers, I do not doubt that the AVERAGE Democrat voter is of higher income level for two reasons:<quoted text>
Nice theory. But if you actually look up the facts, you'll find those voting Repubilician had an average income of $18,800. Those voting Democratic had average income of $28,000, as reported by Slate. I've seen other sources that say similar things. But who wants the facts now days.
1. Republicans tend to do well in rural areas which typically have a lower per capita CASH income.
2. The SUPERRICH such as Bill Gates, Warren Buffet, John Corzine, movie actors etc overwhelm the averages. They make in the 100's of millions each year and they know that the true path to their continued dominance of the poorer classes is to support Liberalism which purports to help the downtrodden but in reality works to keep them in their place.
