After undergoing her final round of chemotherapy for the brain cancer that ended her mayoral bid in 2014, she’s baaack! And feistier than ever, taking aim at Rahm, Rauner, and CPS head Forrest Claypool ([[[No. 32]]]), who she says knows “nothing about education.” Lewis’s powerful union voted in December to authorize another strike after contract talks stalled, but it remains to be seen how effective a teacher walkout would be if the broke district doesn’t get the state funding it needs. Rauner has suggested bankruptcy; Lewis has called the idea “very irresponsible.” Be warned, Mr. Governor: This woman has a history of getting what she wants.
