I don't think so, Obama could care less about them. I think he's smart enough to know pardons for these two would stick with him the rest of his life, and hamper his future earnings.
If it was any other Lib than Obama...I'd agree with you.
But look at what he's doing right now. He's emptying prisons of felons...he's going to have Gitmo empty of even the most violent offenders before he leaves office.
In short...he doesn't give a rats ass what we think about what he's doing. It's not going to hamper his earning IMHO because there's plenty of Liberal think tanks media outlets etc that will pay him huge sums of money to be associated with them.
Combine that with the fact he's not worried about ever being elected to anything again in his life and you've got the perfect combination for someone to do just what I think he's gonna do.
