Plus, there's chatter that fans will also see the return of Matthew Perry, who played Mike Kresteva, the Republican candidate for governor who lost to Peter Florrick (Chris Noth). Peter's win makes Alicia (Margulies) the first lady of Illinois and her new position is one reason the character decided to leave Lockhart/Gardner with Cary (Matt Czuchry) , Margulies said.

"I really think Alicia is not doing it out of any facetiousness. I think she's doing it out of survival and knowing that she has to get away from Will and out of the shadow of Lockhart/Gardner in order to really commit to being first lady," Margulies told ETonline .
