McCain is pulling really desperate shit in Iowa. Yesterday, the college GOP tried to rally supporters. They had a big posterboard that said "Hitler's Holocaust" with a liberated concentration camp. Then below it, it said "Obama's Holocaust" and it had a wide variety of pictures of dead fetuses. It was offensive but it was funny, considering that they have to resort to this to whip up GOP support. Nobody paid attention to them and just kept walking.
I think the only reason why he remains in Iowa is that it has been a swing state for the past decade. However, the state is solidly Obama territory.
I think McCain's new areas to visit will be Florida, Ohio, Indiana, Nevada, and North Carolina. Maybe Colorado. I could see them go either way.
