Kildor is right that the winner will be $. Obama and McCain, to use a vulgar analogy, same sh!t, different a55holes.
Both are sponsored by huge corporate interests, both support the pheony War on Terror based on lies and government-sponsored terrorism, both want to attack Iran, even though the US Intelligence Community knows that Iran has no weapons program since '05, that even that may be a lie to establish that Iran had hostile intentions. Besides enriching uranium is a right under the NPT.
Whichever side wins, they're just two wings of the same bird. You know what hope is? It's something intangible within every American, as well as in every person in countries where elections are held, that gets crushed every four years.
