Exceptionalism as Foreign Policy

Let me offer a (probably) simplistic view of the differences in foreign policy between conservatives and liberals.

Conservative voters, I think, tend to view America as an exceptional land. As such, the foreign policy of our country must perforce be, if not perfect, at least the best attempt at it. The view of liberal voters is that it is only due to the actions of our country that we are exceptional, as because of that, we need to be sure that we take actions that make our exceptionalism a positive, and that it is way too easy to "go to the dark side" and use our exceptionalism as a borm of bullying.

To put it even simpler, a conservative believes that because it is our foreign policy then we need to support it. A liberal believes that because it is our foreign policy it is crucial to turn the most critical eye upon it.
