Former Senate Majority Leader Bob Dole is set to campaign with fellow Republican Pat Roberts in race that’s suddenly competitive for the three-term Kansas U.S. senator.

Dole planned to attend an event with Roberts Monday in Dodge City, where Roberts lists his residence but admits having visited only seven times this year. The pair also plans to attend events together Tuesday in heavily Republican western Kansas.

Having eked out victory in a GOP primary in August, Roberts finds himself locked in a tight race with Greg Orman, a businessman from the Kansas City suburbs running as an independent.

Roberts revamped his campaign team at the request of national Republican Party officials this month, when polls showed the race tight, and Roberts with little general election organization.
