Blagojevich faces the prospect of 10 or more years behind bars. Prosecutors will be asking for 15 to 20.
Judge James Zagel is expected to decide on a sentence on Wednesday - possibly so he can sleep on it. If Zagel sentences Blagojevich to more than a decade, it would be one of the stiffest penalties imposed for corruption in a state with a long history of crooked politics.
The disgraced former governor has already paid a price in public ridicule and financial ruin. The defense plan to insist that Blagojevich is innocent, and that he should only be sentenced to a few years.
Legal experts say Blagojevich needs to display remorse, but it was unknown if he plans to beg for mercy, or protest his innocence.
