But, Dillard says he's not like any of the others. He calls himself "Illinois through-and-through."
Dillard has served in the Illinois State Senate since 1995. He served as Chief of Staff for former Illinois Governor Jim Edgar before that and is a practicing attorney. Dillard says he is a fiscal and social conservative and would focus on improving Illinois' business climate if elected. He's says he would not raise income taxes and is in favor of a flat tax.
"The state is in the worse shape today than it was a few years ago and they're looking for somebody who has a proven record of getting a democrat legislator to do things that it's not in their DNA to do," said Dillard.
Sen. Dillard is the fourth republican to announce a run against democratic Governor Pat Quinn since June. Also running are Illinois Treasurer Dan Rutherford, State Senator Bill Brady and venture capitalist Bruce Rauner.
This is Dillard's second run for governor. He lost the Republican Party nomination in 2010 to Senator Bill Brady.
