The Obama campaign did such an amazing job marketing itself and it really shows that the power of a logo is its simplicity. The others were all more relevant - most of them were more topical with the "'08" or "change" in them, but the final logo just works so well. Obama's logo reminds me a little of Bank of America's. They both evoke an image of the American flag as well as farming/middle America (BofA's logo looks like farm plots to me and the red/white stripes of Obama's logo make me think the same). The blue semi-circle looks somewhat like the arc of a rainbow over the horizon evoking (for me) a hopefulness that something is better over the horizon and an idea of inclusiveness. It's one of the best logos I've seen. I'm guessing he'll use it again in 2012 as it's an instantly recognizable symbol.
