What excites and frightens at the same time is how close the man is to actually winning. One doesn't need to be in the 'States to taste the electric tang of change and as-of-yet unrealized potential. It's almost like asking someone out: so many things can skew things and make the whole effort another punchline in yet another existentialist joke.

I'm watching the US elections out of the corner of my eye, devoting a bit of brain power to extrapolating alternate future histories ("What happens if McCain or Obama wins?") from insufficient data. I might as well try to number crunch those futures just to keep my mind occupied. Beyond my jobs what else have I got to do?
