And completely out of agreement on the big picture - i.e. America's role in relation to and interaction with the other nations of the world. Kucinich and Bush both favor ceding U.S. interests at times for the greater good of the "world community," believe that the United Nations serves a useful purpose, and believe in the role of international "peacekeeping" forces to keep order (though they sometimes disagree on the locations. Paul does not.
I think it’s a real stretch to compare Kucinich to Bush. Consider the fact that Iraq happened without UN approval.
Anyways, if Paul is so different than Kucinich, how come they vote in tandem on almost all foreign policy bills in Congress?
