Radogno served as the Minority Leader, the first female leader of a political party in the Illinois Legislature. She resigned from the Illinois State Senate on July 1, 2017 amid the Illinois budget crisis.

In 1996, she ran for the Illinois State Senate and narrowly defeated incumbent Robert Raica in the Republican primary. In 2006, she was the Republican nominee for Illinois State Treasurer and was defeated by Democrat Alexi Giannoulias.
