Mr. Natural is a member of neither political party, nor has he heard of them. However, his chronic presence on the sidelines of national politics forces both parties to hew, or "truck," toward the center, and eschew fractious discourse in favor of a simple, clear message with wide appeal. Though he has come to be associated with the use of marijuana and other semi-illegal substances, his actual message was advocacy of the state of mind to which he lent his name, the apocryphal "natural high," which one can attain without smoking marijuana at all, provided enough other people in the room are.
