Can Obama give him an executive pardon at the end of his term?
Yes, Obama can pardon him. It is my likely that he pardons Retzko, that is the guy who took the fall. Retzko was playing two schemes at once, Obama and Blago ... not the same schemes. Big mistake, Blago thought it was one in the same. Blago thought he was a Rham guy, in the end Rham gave Blago to the wolves
