After some deliberation, I've decided to support Kennedy. He's the only one that has confronted Rahm and the Machine over their failures on issues of gentrification, gun violence, and corruption. Biss has done none of this and yet has earned the support of many progressives by giving lip service to "free college." Insanity.
I don't like Rahm that much, and Kennedy seems to be the most viable alternative to Pritzker. I will support Kennedy unless he has a scandal that makes him unacceptable to me or Biss receives a massive burst of support that puts Kennedy in 3rd place. I doubt either scenario will occur.
