A Chicago-based printer with ties to the Democratic Party printed campaign mailers that targeted county-level Republican primary candidates, according to a Northwest Herald story. But the group that funded the mailers, Illinois Integrity Fund, remains a mystery; even a Hoffman Estates address used as the return address on the mailers could be bogus.

A post-primary poll shows that re-election prospects for incumbent Gov. Bruce Rauner look bleak. An Odgen & Fry survey shows him down 22 points compared with Democratic nominee J.B. Pritzker, and in an almost certain death knell for a politician, Rauner’s unfavorables are nearly double his favorables.
