You've probably seen Harder Better Barack Obamers, and just this AM I introduced you to Biden's lustful a capella fan club, but the musical Dear Johns keep coming this election season. CASE IN POINT -- the following rap vid that starts off like a school history project before quickly turning into a crunked-on-Obama, awesomely cocky elementary school rump shaker that THEN kind of turns into a White House coup. Neat.
