After Obama has gone after reporters for leaks, and after Snowden....
Nah. Obama will NEVER go easy on Manning.
He doesn't have to, it won't get to his desk for about three years after the mandatory appeals and reviews. The Prez doesn't touch court-martial results for a non-capital case until all the appellate procedure and lower clemency determinations are out of the way, and then only as a pardon request.
However, with all due respect and coming from someone who generally agrees with you, if that was sarcasm it was too subtle. Leaks are pursued by this Maladministration in direct proportion to how much they piss off and embarrass Obie-One, and not for any other silly little reason like what exactly was compromised, whose covers did it blow, did anyone get killed as a result, and how badly did it damage our foreign relations and future operations.
