The Gitmo thing is purely a dog whistle for those who hate the president - plain and simple. Had he closed it, you'd be having a stroke that he "brought terrorists to our land". Had he left it open, he broke a promise and can't get things done.
Politifact is quite up front about promises that Obama has broken, but there's a ton of promises he made that he's kept as well. None of it matters to folks like yourself though, when you have "trusted" news like Fox News spinning things like improving unemployment numbers (the extra obvious 2 lines are mine to show where they fudged the graph) - it's no wonder people are so uninformed.
