Another task of the republican party would be to give a bad name to free market capitalism and christianity, IMO. Or at least some of the higher ranking ones, that is.
I also like to compare american politics to professional wrestling. The republicans are the "heel", and the democrats are the "face". As the match begins, they begin shouting at each other, quarreling over emotional sensationalistic shit that shouldn't matter to anyone. Chairs go flying, people get put through tables, and the crowd can't take their eyes off (this is key). But who will ultimately win? The same person wins every single time.
Vince McMahon the owner of WWE of course. After staging the script, the wrestlers go backstage to pat each other on the back, take showers, and probably go out for a drink. Meanwhile, the audience was so hypnotized by the show, they didn't pay attention to the flat $5 cokes or the $40 T-shirts.
