Uh...  Obama DID try to close Gitmo but when he wanted to move captives to America congressional Republicans wet themselves in fear and refused to let it happen. Obama did get out of Iraq, within the terms of the force reduction agreement Dubya's administration set. If he'd left Afghanistan you'd be complaining that he let the turrists win just like Republicans did when he honored Bush's Iraq treaty. I'm certainly no Obama fan because I think he caved to Republican fear mongering and did not take a principled stand on civil liberties but he did get through the majority of his campaign promises. That's a fact. The ones he didn't get passed were generally because of Republican intransigence and obstructionism.

And then you have Mr. Trump. He's pussing out on his promises before he even has a chance to try to make them happen. Which leads me to believe he only promised things like ACA elimination and wall building as 'campaign devices' (Thanks, Newt!) to sucker gullible, low info voters.
