If you wanted to do the research you could follow the connections of mentors, friends, and influence from Capone to Blagoyavitch and Obama.
http://en.wikipedia.org/wiki/Governor_of_IllinoisSix Illinois governors have been charged with crimes during or after their governorships; four were convicted, and of those, one (Blagojevich) was first impeached and removed from office.
[edit] Acquitted
Len Small (R), governor from 1921 to 1929, was indicted in office for corruption. He was acquitted; thereafter, eight of the jurors received state jobs. Among his defense lawyers was former governor Joseph Fifer, who asserted, in pre-trial hearings, that the governorship has the divine right of kings.[3]
William G. Stratton (R), governor from 1953 to 1961, was acquitted of tax evasion in 1965.[citation needed]
[edit] Convicted
Otto Kerner, Jr. (D), Stratton's successor and later a judge on the United States Court of Appeals for the Seventh Circuit, was convicted of 17 counts of bribery, conspiracy, perjury, and income-tax charges from his time as governor,[4] and received 3 years in prison and a $50,000 fine in 1973. He was prosecuted by future Illinois governor Jim Thompson.[5]
Dan Walker (D), governor from 1973 to 1977, was later involved in the Savings and loan scandals and convicted of federal crimes related to fraudulent loans to himself from his own First American Savings & Loan Association of Oak Brook. He was sentenced to seven years in prison with five years of probation following his release.[6]
George H. Ryan (R), governor from 1999 to 2003, was convicted in 2006 of corruption related to his time as Illinois Secretary of State in the 1990s, when commercial driver's licenses were issued to unqualified truckers in exchange for bribes, and one of the truckers was involved in a crash that killed six children. Former governor Jim Thompson, whom Ryan had served under as Lieutenant Governor of Illinois in the 1980s, was manager of the law firm that defended Ryan.[citation needed] Ryan is slated for release in 2013.
Rod Blagojevich (D), governor from 2003 to 2009, and Ryan's successor, was impeached and removed from office by the Illinois General Assembly in a unanimous vote in January 2009 after being tied to multiple "pay to play" schemes.[1] In August 2010, he was convicted of lying to the FBI in connection with the investigation, but the jury deadlocked on 23 other charges.[7] Blagojevich was retried on 20 counts from his 2010 trial and on June 27, 2011, Blagojevich was convicted on 17 counts of fraud, acquitted on one count and the jury was hung on two.
