When voters pick their next senator, they'll likely just be choosing who they trust more.
The race between Mark Kirk and Alexi Giannoulias has been filled with personal attacks. Kirk has been accused of lying on his military record. Giannoulias has been accused of doing business with criminals at his family's bank.
UIS political science professor Michael Miller says Kirk has the advantage in the credibility game so far. He came forward and admitted he lied.
Giannoulias has jumped around his problem, Miller said.
Miller says you can expect to see more negative commercials until election day.
Miller's comments were featured in an October 19, 2010, report by WCIA-TV Channel 3.
