1) Obama is against jailing enemy combatants so instead of capturing and holding them without trial indefinitely, he's shifted policy to just outright killing them. This is reflected in his attempts to close Gitmo, his drastic increase of the drone programs, his emphasis on Special Forces (Biden's pet strategy), the execution of the Pirate Hostage takers, the execution of bin Laden.
2) When he came into office he was adamantly opposed to Gitmo remaining open. He either was unable to close it, or he changed his mind.
If he was unable to close it, this is not the fault of Obama. People against Gitmo were still right to vote for him. He championed the cause the best he could but was thwarted. We don't have kings in America, so if it's an issue you feel strongly about, you should vote accordingly, not just for President but for Congress as well.
If he changed his mind, that tells me something about the issue, not Obama. It seems like he took a politically weaker stance by not closing it down because it pisses off his base and arms his opponents with claims of his impotence. So I don't think he was motivated by politics to change his mind. What, then? I'm guessing it would probably be that he's privy to information he hadn't had before he took office.
So for me, who doesn't have much stock in Gitmo closing, it makes sense that we should be shutting it down, but only after it's feasible. I'd rather suffer "moral" harm to the country than physical.
