Democratic Gov. Pat Quinn and Republican Bruce Rauner are setting up a big-money battle to become Illinois’ next governor.

The candidates released campaign finance reports Tuesday for the three-month period that ended June 30.

They show Quinn raised about $3.7 million in that period and has about $12 million in his campaign fund.

Rauner raised more than double Quinn’s total in the second quarter but spent much more, leaving him with about $3.5 million. But the multimillionaire businessman has the ability to raise millions more. He’s already given more than $6 million to his own campaign.

Last month, Rauner also received a $2.5 million donation from Chicago hedge fund CEO Ken Griffin. That’s believed to be the largest single Illinois campaign contribution in the post-Watergate era.

Quinn’s campaign says more than two-thirds of his 1,357 donors gave $100 or less. But among his biggest contributors are labor unions and the Democratic Governors Association.
