I'm not arguing that some of Obama's policy implementations are lacking. But it seems like people are expecting too much out of him.

I think that solitary confinement is definitely unethical. But I also think the idea of mass pardons for prisoners if states don't reform solitary confinement would be political suicide. Republicans would be running ads saying that Obama wants violent criminals to be released because prison isn't comfortable enough. Democrats wouldn't support it. And I think it might sink the democratic party's chances in the presidential election. Sure there are more things that Obama could have done to solve specific problems. But I don't think some complaints would have been fixed under any president.
