Federalists vs. Anti-Federalists

This is a fascinating 4 minute overview of the Federalist and Anti-Federalists.  In a sense they are examples of early interest groups.  The Federalists were better known as nationalists or centralists and the Anti-Federalists were really the federalists.  But the Nationalists thought they would be better liked if they were the "Federalists" and their opponents were just "anti-."  Furthermore it is interesting to note that the Federalist were much better organized since, by definition, the Anti-Federalists just plain didn't want to work with one another
