At one point before the end, NBC was showing state-by-state results and a McCain state was on the screen. Elliott saw it and said, "Uh oh Mommy, John McCain won, look!" I tried to explain about state vs. national results but I think he was already back to playing with other kids before I could finish.
By the time they called it, he was blinking and groggy from sleepiness - it was way past his bedtime, especially with the recent time change - but he clapped and cheered "O-BA-MA! O-BA-MA!" with the rest of the crowd. And then we went home and tucked him into bed.
