"It sounds like the revolution has arrived in Illinois," presidential candidate Ron Paul said. "I'm excited to be here with you."
More than 5,000 people turned out to hear Paul.
The message: limited government and more individual freedoms.
"The government is too big, our liberty is too minimal and that is the reason, the solution is shrink the size of government and give you your liberty back," Paul said.
Applause grew as Paul made a demand to end wars overseas.
"The foreign policy has to change, the war has to end and we need to bring our troops home," he said.
Ron Paul is in last place among Republican presidential candidates. Supporters say they are still hopeful.
"The enthusiasm, the excitement. They say he's unelectable, but there's 5,000 people here. How is he unelectable?" supporter Chris Shefner said.
It's momentum Paul hopes carries over nationally.
"I told there would be friends here, we'd have enthusiasm, but this is beyond my expectations," Paul said.
All of the other Republican candidates are expected in Illinois before the primary. Rick Santorum will be in Effingham on Saturday. Mitt Romney and Newt Gingrich will hit the Chicago area before Tuesday.
