This image is, to my mind, wonderful from a purely visual perspective -- it's verticality signaling achievement and ascendancy, the index finger as a symbol of victory, the dexterity required to spin a basketball as a sign of skill and grace -- but it is also great because it references the red, white and blue ball used by the American Basketball Association. What an awesome way to simultaneously subvert and take full advantage of the unwritten rule that political marketing has to reference Old Glory in some fashion.
