Earmarks for 2008 (so far) accounted for $13.2 billion. 2005 was the worst, reaching somewhere over $25 billion. However, total federal spending is well over $2 trillion mark, almost approaching $3 trillion.
http://www.fedspending.org/I'm for removing earmarks, but if we reject every bill that has pork, a lot of necessary funding for public services is going to get cut. When you look at it in perspective, earmarks are peanuts compared to how much the government spent on the war and corporate welfare. (Freddie May & Fannie Mac being the most recent example) Cut those two out first.
