U.S. Sen. Pat Roberts says the most important issue for Kansas voters in his re-election race is helping fellow Republicans win a Senate majority.
During a debate Wednesday, independent candidate Greg Orman accused the three-term incumbent of spreading "falsehoods" in trying to portray Orman as a liberal Democrat.
Roberts and Orman had their third and final scheduled debate at the studio of Wichita station KSN.
The race has received national attention since Democrat Chad Taylor dropped out last month, making Roberts more vulnerable and jeopardizing Republicans' drive to recapture the Senate.
Orman is running as a centrist. He opened by saying that both political parties are more interested in playing games than solving problems.
Roberts countered by saying that a vote for him is a vote for a GOP majority.
