Down by five points in the latest poll, Sen. Pat Roberts (R-Kan.) is calling in every big-name Republican for some extra help in closing the gap.

But none are as big -- in Kansas -- as Bob Dole. At 90, the former GOP presidential candidate and long-time senator remains a beloved figure, with approval ratings at 73 percent in the Sunflower State.

Roberts's opponent, Greg Orman, has said that he sees himself in the mold of Bob Dole. This ad blunts that argument, as Dole refers to Roberts as his "good friend" and essentially says: Greg Orman, you're no Bob Dole.

Of course, not everyone is pitching in for Roberts. Moderate former Republican senator Nancy Kassebaum Baker reportedly declined to cut her own ad for Roberts.
