Whatever Trump did or didn't do, didn't compromise our national security or expose our people to death at the hands of terrorists. He wasn't bought by multi national corporations or foreign donations.
NOR IS ANYONE PROCLAIMING HE'S FOR LESS GOVERNMENT
Obama had squat clue about foreign policy as well, and thanks to him and Clinton, we now have the inferno, referred to ISIS
Point being, its not Obama's place to call the primary nominee of the opposing party "unfit". Clinton can...all her cool-aide drinking sychophants can. The President should refrain, in the event that Trump wins
