WICHITA, Kan.--- Candidates for the U.S. Senate seat to represent Kansas are challenging incumbent Senator Pat Roberts.
"These primaries can get pretty intense and pretty bitter because they're really not about the party," said Ken Ciboski, Wichita State University political science professor.
D.J. Smith, Milton Wolf, and Alvin Zahnter are three Republican candidates running against Roberts.
Of the group, Senator Roberts and Dr. Wolf have been spending their campaign funds on several television advertisements aimed at each other.
Wolf's advertisement attacks Roberts on the length of time he has been in Washington, D.C. rather than in Kansas. An excerpt from Wolf's advertisement said, "After 47 years in Washington, Kansas is a distant memory for Pat Roberts."
Roberts' advertisement attacks Dr. Wolf on professionalism. An excerpt from Roberts' advertisement said, "Wolf exposed private patient x-rays and other personal information on Facebook, where Wolf relentlessly poked fun at the dead or wounded."
"Who these individuals really are, I think, that's what it's about. I don't think it's about issues and that's kind of sad," said Ciboski. "Issues should really be at the center of a campaign."
Chad Taylor and Patrick Wiesner are the two Democrat candidates in this Senate race.
Greg Orman is running as an Independent and his television advertisements started airing today.
The state's primary elections will be held on August 5.
