The good folks at CQ Politics have assembled a list of the 32 politicians most likely to be John McCain's VP choice and have put them in a bracket. You can vote on who advances from each round. If you have no problem with momentarily trivializing one of the most important choices we make as a country (and quite literally turning politics into a game), go try it out. I did.
By the way, the 32 candidates include four women, five people of color, and 24 white dudes. Considering the state of the modern GOP (no African-Americans in Congress), that's not bad. The fact that Condi is involved really boosts their diversity numbers.
