I’ve said that politics in the United States is a competition for jobs, with no higher principles involved. It’s like watching a crowd of grimy contestants try to catch the greased pig at the county fair.

Here’s an excellent comment on the shallowness of it all. I recommend the entire article.
From “A Measure of Morality in Congress”, by David Swanson . . . who says that members of Congress most often vote as they do “in order to keep their committee chairmanships, or in order to receive funding for projects in their districts, or in order to receive assistance or not face opposition in their next reelection campaigns.”
“What's the worst fate a Congress Member could face as a result of voting against funding the war? For most it must be the loss of their seat. How horrible is that? Some of these congress members are freshmen, first elected last November campaigning on promises to end the war. Now they're prepared to vote $100 billion for the war in hopes of getting elected again in 2008. What in the hell did they want to get elected for in the first place? What district is going to receive less money if we end the war and redirect our spending to useful projects than if we continue the war but fund special pieces of pork here and there?”
