The decisions by both Olivo and Quinn to file nominating petitions raised eyebrows because both are so close to the speaker. But the 13th Ward Democrats last month told Sun-Times columnist Rich Miller, who also runs the Capitol Fax newsletter and blog, that Olivo was "awaiting final clearance from physicians" to seek another term.
"Quinn filed as a precaution," Miller reported. "The expectation is that Olivo will run and Quinn withdraws."
That didn't happen, and Olivo has decided to put his health ahead of public service, a Madigan spokesman told the Sun-Times.
There's been no public comment from Olivo or Quinn.
