I can understand how being a governator or in Congress can give you the warm fuzzies, but it has nothing to do with being a good leader. To me, a good leader simply surrounds themselves with intelligent people and is mostly just a logic gate for ideas. No one person can run this country.
Additionally, Washington suffers from a serious issue of group think. I think and would LOVE an outsider's point of view on the situation. Being that he's made it in Hollywood, he's also likely a smart and persistent guy. Smart? SOUNDS GREAT!
Finally, our political system IS a fucking joke. Just sit back, RELAX, and laugh, as we have the freedom and ability to do so.
