It was only a matter of time before a federal probe hit former Illinois governor Rod Blagojevich’s wife, too. Here’s part of the story from Thursday’s Chicago Sun-Times:

Federal authorities have hit former first lady Patti Blagojevich with a federal subpoena dealing with recent charges lodged against her husband, raising new questions over whether she will become part of a grand jury indictment expected by early April.

The subpoena, with which Patti Blagojevich reportedly complied, asked for any documents, notes or e-mails she had related to more than 40 people or entities — from former gubernatorial fund-raisers Tony Rezko and Chris Kelly to her own real estate dealings.

Patti Blagojevich’s lawyer, Raymond Pijon, told the Chicago Sun-Times that federal authorities have great discretion over whether to charge her — and that he hopes they’ll consider the “family structure” as they weigh that decision.

“I’ve seen it happen on a number of occasions; they elect not to bring in other family members,” Pijon said.

Just because she has been cooperative doesn’t mean she’s going to flip on her husband, her lawyer said.

“I think they’re close as a couple and obviously have a lot of things in common,” Pijon said.

Federal investigators have been scrutinizing Patti Blagojevich’s real estate dealings in recent years.

If Pijon is right that charges may not be brought against Patti Blagojevich for the sake of her two young daughters, the former first lady will be awfully lucky. If she was involved with shady real estate dealings that sent others to prison, she should be punished, too — at least with a significant fine and suspension of her real estate license.

Pijon certainly is correct about Rod and Patti having “a lot of things in common.” The Blagojeviches are both unemployed, foulmouthed, defiant and crooked.

And neither has a snowball’s chance in hell to win in the court of public opinion.
