There wasn't supposed to be an election for a statewide constitutional officer this year. But Democrats essentially forced one, following the sudden death of Republican Judy Baar Topinka after she'd won the 2014 election for comptroller, but before she'd been inaugurated.
The race has been expensive and competitive, and it could show who's winning the war of public opinion between Gov. Bruce Rauner and Democratic House Speaker Michael Madigan.
Who knows what would have happened had Democrats held onto the governor's office in 2014?
