A former math professor who reported income of less than $35,000 last year is campaigning as a middle-class candidate in an Illinois governor's race that includes a couple millionaires and a billionaire.
Daniel Biss likes to tell people he's given his campaign just $25 - and then his wife decided to one-up him and donate $50. He jokes they're "pretty well maxed out."
Biss seems to be gaining support for his progressive campaign.
In TV ads filmed in his family's modest home, he talks about sending his kids to public school and living on a budget. In another ad, he links wealthy Democratic rivals J.B. Pritzker and Chris Kennedy to two Republicans, Illinois Gov. Bruce Rauner and President Donald Trump. He calls them all "rich guys" who've avoided taxes.
