Less than an hour ago, walking from my office in the West Village to the Q train in Union Square, I heard constant shouts, cheers, and chants; passed a young woman singing the Star-Spangled Banner; and saw more smiling faces than I've ever seen on a New York street -- or any street, for that matter. My wait for the train was accompanied by still more screams and yelps of joy, as each new group of people descended the stairs into the station, giddy and enthusiastic.

I stepped onto a Brooklyn-bound Q train not long after 1am. There was a short, five-second awkward silence. Then a young woman screamed "Obama!" and the entire train car erupted into raucous applause.
