He's a political outsider, and that's why Bruce Rauner thinks he can turn Illinois around.
"The state has companies leaving, jobs leaving, taxes rising and schools deteriorating, and I firmly believe that career politicians, after battling for so long in Springfield, will never turn it around."
And if the republican becomes governor, he says one of the first things he'll work on is implementing term limits, to put an end to what he calls career politicians.
And Rauner says special interests won't get their claws in him.
"I'm gonna come in as an independent guy, financially independent, a self-made businessman, passionate about lowering our taxes and having a booming economy in Illinois."
Rauner, a Chicago businessman, will have plenty of competition in the republican primary.
Also running are State Senators Bill Brady and Kirk Dillard, and Illinois Treasurer Dan Rutherford.
