I think the issue is that he can't just sit by and watch. Kucinich also has this motivation. Not everyone feels content just watching the world crumble as they do nothing.
I highly doubt the system in Washington is impossible to fix. The US Constitution was written to provide means that if a large enough majority wanted it, any change in government necessary could be made to deal with issues at hand. While this has both it's pros and cons, it's pros highly outweigh the cons.
The largest problem is to get changes made is convincing people to stop pointing fingers about who's fault the problem is, and instead just deal with the issues at hand.
Personally, there is only one philosophy I take, and due to it's vagueness, all others I study to put in it's context. It is the simple original Christian philosophy of "love one another as yourself" that so many self-proclaimed Christians ignore in favor of the "eradicate evil" philosophy that dominates the world.
