Tresser -- a leader of No Games Chicago -- won a big victory when the city lost its bid to host the 2016 Olympics. Now he hopes for a huge political upset.
The self-described community activist is the Green party nominee for board president in Cook County, one of the country's most Democratic counties.
Tresser teaches public policy and civic engagement at DePaul University and the Illinois Institute of Technology. He's a former theater producer, and he consults for nonprofit organizations.
His platform includes eliminating the remaining half-cent of the one-cent sales tax hike that was pushed through by board president Todd Stroger.
Tresser pledges to eliminate patronage and waste, and claims he can cut property taxes by 10 percent.
He would open storefront health centers staffed by nurse practitioners. He says he'll fight for better housing, schools, and transportation. And he hopes to expand urban agriculture, to provide both jobs, and fresh, healthy food.
