I think mayze has it the wrong way around. You are more likely to be a Republican if you are white, Christian, and have a high socioeconomic status. This is the Republicans targeted socioeconomic status. Socioeconomic status is to politics what target demographics are to marketing. In the United States the Republican party goes after the White Anglo-Saxon Protestant market. They typically have more money and belong to a higher socioeconomic group. The Republicans offer tax cuts and programs aimed to benefit this group in order to win their vote. The Democrats, on the other hand, try and appeal to people of middle to lower socioeconomic groups by offering policies and programs that would benefit those groups the most. Both parties don't try too hard to market themselves to people who aren't in their targeted socioeconomic group. If you’re not in the target demo, you don't count. In the end it's not too different from corporate marketing.
