Maybe I'm wrong. but I think Ford was President when we evacuated Vietnam. OTOH, Carter had the embassy hostages and the failed rescue attempt (gut the military and unpleasant @#$% becomes more likely!).
Ford didn't get elected in 1976, and Carter was a one-termer - and a failure! - which is the point you were making, zg. Americans don't like foreign policy gross failures, and BHO's foreign policy is shaping up to be an epic fail. Come January BHO and Moochchelle will walk out of the WH and onto the rubber chicken circuit or book-advance solicitations. The people who will have do the work to try to set aright BHO's utter mess probably won't fare so well.
