The disgraced former governor of Illinois, Rod Blagojevich, faces a sentencing hearing Tuesday on 18 counts of corruption, including trying to auction off President Barack Obama’s old Senate seat.The impeached governor-turned-reality TV star has good reason to feel anxious at the two-day hearing in Chicago: He could face 10 or more years behind bars.If Judge James Zagel settles on a sentence Wednesday of more than a decade, that would make it one of the stiffest penalties imposed for corruption in a state with a long history of crooked politics.Prosecutors will ask Zagel to imprison the twice-elected governor for 15 to 20 years, arguing he has not only shirked all responsibility for his crimes but repeatedly thumbed his nose at the US justice system.Blagojevich has already paid a price in public ridicule and financial ruin, the defense argues in proposing a term of just a few years. They also seem bent on an approach judges often frown upon at the sentencing stage: Continuing to insist their client is innocent.Both sides could finish their pitches to Zagel during Tuesday’s hearing, which was moved to a large ceremonial courtroom to accommodate expected crowds. But Zagel says he’ll wait until Wednesday to pronounce a sentence.The 70-year-old judge must answer nuanced questions according to complex sentencing algebra, including whether any good Blagojevich accomplished as governor counterbalances the bad.In describing the humiliation his family has faced, the defense cited Blagojevich’s appearances on NBC’s “Celebrity Apprentice,” where he struggled to use a cell phone, and his wife, Patti, eating a tarantula on the reality show, “I’m a Celebrity...Get Me Out of Here!“After sentencing, Zagel will likely give Blagojevich weeks before he must report to prison. Once there, the man heard scoffing on FBI wiretaps about earning a low six-figure salary would have to take a prison job at just 12 cents an hour. Blagojevich’s sentencing comes just days before his 55th birthday and three years to the week of his Dec. 9, 2008, arrest.The jury deadlocked in his first trial, agreeing on just one of 24 counts — that Blagojevich lied to the FBI. Jurors at his recent retrial convicted him on 17 of 20 counts, including bribery.Legal experts have said Blagojevich needs to display some remorse when he addresses Zagel.
