These dead presidents' faces are the only things valued in our US culture right now. This last group is the change we can believe in - as far as presidential races go. That is all.
Update: Dead presidents = money as conversational shorthand. Since I am in a wordcraft mode - or sound bite mode - I heard another phrase I also want to share. McCain is a standard drill and burn republican. Drill and Burn is pretty succinct. h/t Grist
Update 2: And yes, they do all happen to be rich, old white men. (You may argue that Kennedy wasn't old - but any young people would disagree). Whether all are xtian or straight is more difficult.
