True. Although I disagree somewhat with Paul on Iraq (I think that once we invaded, we obtained a moral responsibility to do the best we can to stabilize the country), it is indeed bizarre that non-interventionism is now seen by many as a leftist cause. I suppose that is really as a result of Vietnam, which leftist radicals opposed for ideological reasons (they wanted the commies to win). Prior to that, non-interventionism was always seen as a rightist cause.
Exactly correct!
I see this as part of the fruit of always trying to compromise with the Left instead of trying to defeat them. The GOP has now moved so far Left that its traditional stands are considered too radical by a lot of its members.
