Narcissistic, arrogant, egocentric, self-serving, megalomaniac. Did I miss any? This is further proof that the two party system is a failure.
I suppose by biggest beef with the two party system is that cannot get behind all, or even most, of either camp's ideologies. That is to say that the far right and left radicals of the parties share views I just don't subscribe to. Take for example the Republicans: Homophobia, racism, bible thumping, fear of scientific advancement are a few named problems I have with the far right. I believe the two party system no longer serves the interest of its people as evidenced by the growing numbers of the independent party. The problem we have now is the "us versus them", zero sum politics that we have allowed outside investors (see big business) to influence. Edit: I forgot to mention another real problem for me is voter apathy and strategic voting just to be sure the other guy doesn't win, even if your guy is a real fucking asshole.
Said much more succinctly than I could do after two vanilla bourbon manhattans. For your thoughts on the global hegemony, take Parag Khanna's The Second World. Khanna explains how the U.S. gained much of its prowess after the collapse of the Soviet Union, but has been handing it over to the EU and China in spades ever since. He also says that global influence is centered on resources, stability, power, and conflict and that the United States'power comes from military power and the enforcement of what it views as basic human rights. That is the scary part. We go around policing the world based on the ideals of some fringe member of our society. Meanwhile, second world powers like Russia, Saudi Arabia, and Turkey are cleverly allowing the big three (US, China, EU) to duke it out, while they gain deeper control over the areas around them. Although the U.S. economy has seen better days, the global economy isn't slowing down and foreign investors are getting better ROI from second world markets than U.S. markets.
