Da Coach has weighed in on Da Campaign for Illinois governor.

Ex-Chicago Bears football coach Mike Ditka appears in a new TV ad for Republican candidate Bruce Rauner (ROW'-nur). It aired Sunday during a broadcast of the Bears game against the Buffalo Bills.

The 30-second spot plays off Ditka's reputation as a no-nonsense task master.

Ditka sits across a table and tells Rauner he likes him because he opposes special interests. Ditka slams his clenched fist and adds, "Hit 'em right in the mouth."

When Rauner responds that maybe he's "been too hard" on special interests, Ditka gives him a 10-second, silent stare before barking: "Stick to the game plan, Bruce!"

Democratic Gov. Pat Quinn's campaign responded in a statement, saying "only a billionaire" could afford such an ad.
