Visual design and the campaigns

Every time I see footage of rallies, I'm shocked that Bush (and, to a lesser extent, Kerry) can use such ugly, almost farcical fonts for their signs. They project power in a 1984, Starship Troopers kind of way. I was trying to see if anybody was analyzing this on the web, but didn't have much luck. The best I could do was a blog about social design which had a recent post about a Times article comparing the two campaigns' logos and a post about this amusing painting. I also found the Design Observer blog, which has some interesting stuff.
