It is a common practice to lower expectations before an event. It's a very smart thing to do. If the bar is set high it is harder to exceed expectations. If you set the bar low then you can easily exceed expecations. It's clear which is the right path to take.
If you set the expectation that Obama will win then it is easy for Romney to come out on top.
Smart play by the Romney campaign. It seems that you and others are taking the bait hook, line & sinker.
