I'm going to go with "possibly." End-of-final-term presidential pardons are not subject to quite the same calculus as decisions made during term, i.e. reelection is not a consideration. Obama's constitutional law idealism may have been severely corrupted by the pressures of his current role, but it's still there. I could see him feeling conflicted about Snowden's de facto exile, and thus being willing to issue a pardon in his last hour in office.

Not likely. But possible. P(Pardon) > 0.1 ?
