The WSJ states that this could be Obama's successful going out party (that is if he is re-elected in 2012):
Obama wants the Chicago Olympics to top off his presidency in style. If he wins re-election, he’ll be handing over to a successor six months or so after the Games are held. By the summer of 2016 he will hope business is booming again and he can then present the Chicago Games as his crowning glory and a symbol of recovery on his watch.He's got a ways to go before that will happen, but we could see this logic.
Anyway, this should be an interesting week for Chicago. We will do our best to keep you covered on interesting Olympic info.
