10th District. Robert Martwick, D-Chicago, who was appointed to the Senate in June, stirred controversy last year when he filed a bill that would have made the Cook County assessor an appointed, not elected, position. The bill was a cheap shot at new Assessor Fritz Kaegi, whom voters had supported over machine-style predecessor Joseph Berrios. Martwick says the legislation was a genuine attempt to start a conversation. We’re not buying it. Neither did then-mayoral candidate Lori Lightfoot, who stood up to Martwick at a news conference. We have endorsed Martwick in the past; agree or disagree with him, he is a student of policy who works across the aisle and does his research. But the Berrios-machine protection bill was a slap to Cook County voters who had finally taken to the ballot box to flip the oversight of a property assessment system driven by clout. This time, we’re endorsing Martwick’s opponent, decorated Chicago police Sgt. Daniel “Danny” O’Toole, who says he reflects a more moderate, independent brand of Democratic voter. O’Toole works to combat gangs and drugs in Chicago’s most challenged neighborhoods and says he has tried to be a role model in a Police Department often mistrusted. “We have to expect a lot from people surrounding these kids, including police officers and (faith leaders) and educators.” O’Toole is endorsed.
