Former Democratic U.S. Rep. Jesse Jackson Jr. and his wife, Sandi, pleaded guilty Wednesday to federal corruption and tax evasion charges.

But in the storied and sordid history of Illinois political corruption, they’re also guilty of a lack of originality.

Jackson is not the state’s first congressman to face corruption charges. The Jacksons are not the first husband-and-wife political team to be indicted together. In fact, they were preceded in that honor by the ex-congressman and his ex-spouse who held the 2nd Congressional District seat before Jackson did.
