I understand something keenly about President Barack Obama: he loves basketball. He plays all over DC, apparently. This resonates with me. When I was in DC a while back, I too played wherever I could in the city. The energy of DC fits well with a passion for basketball, which is the most kinetic (and absorbing) of games.
(That, by the way, also makes perfect sense. The true basketball aficionado constantly slips away wherever he can to play the game. Only basketball obsessives will understand.)
