I can't decide which of these tote 'em ups is cooler. The New York Times has a graphic analysis of the top 200 search terms used on both of the candidates' websites — and with abortion topping Barack Obama's and health care heading McCain's it makes me think perhaps web-searchers are using the sites to get info on the opponent? The lists seem a weirdly counter to what one might expect from ardent supporters, but maybe I'm nuts?
Speaking of Congress (I kid, I kid) this is remarkably addictive and enlightening too — it's called CapitolWords, and it uses the Congressional record to figure out the most-used word on any given day. It's a little slice of the American consciousness that's eerie. From June 16 to June 20 it reads, "tax, health, oil, housing, oil." Well, it looks like they're talking about the right things at least? Try it out, but I'm warning you it's tough to stop.
