The heated race for Illinois governor is shattering state records for campaign fundraising and spending.

State filings show Democratic Gov. Pat Quinn and Republican Bruce Rauner (ROW'-nur) have had at least $58 million to spend on the general election so far.

That's about $20 million more than Quinn and Republican Bill Brady spent on the 2010 general election.

Kent Redfield is a campaign finance expert who compiles and analyzes the data. He says the increased spending is a sign of intense national interest.

Republicans see the blue state as a big prize in the Nov. 4 election. Redfield says Rauner's anti-union positions also have energized organized labor, which has contributed millions to Quinn.

Candidates face a Wednesday deadline to file campaign finance reports for the most recent quarter.
