I mean, the crime, conviction, sentencing, and multiple suicide attempts all happened while Obama had the power to commute the sentence. If there was a principle at play here, if Obama thought it was a moral good to have this person avoid a prison sentence, I'm having a hard time imagining what the roadblock was. Was it that the massive leak and subsequent prosecution didn't get enough media coverage, so he was unaware of the situation? No, that doesn't sound right, it was widely known at every stage in the process.
If commuting someone sends a message, the delay sends a message too. Perhaps he's just trying to do the right thing when the consequences won't hurt him. Perhaps it's all for show. But I think it's fair to conclusively rule out the theory about this decision being made in order to maximize the welfare of Manning. Something else was in the calculus here.
