The Republican challenger to Sen. Pat Roberts, R-Kan., thinks nobody should spend 47 years in Washington.

Dr. Milton Wolf, a diagnostic radiologist from the Kansas City area, on Wednesday released a television ad criticizing Roberts for his nearly five decades in the nation's capital.

"After 47 years in Washington, Kansas is a distant memory for Pat Roberts," the ad opens, before pivoting to Wolf's daily routine as a Kansas doctor.

The ad goes on to mention Wolf's plan to "repeal and replace Obamacare," "fight wasteful spending" and pass congressional term limits.

After his tenure, Wolf's ad promises, he'll return home to Kansas.

Wolf, a Kansas native, is President Obama's cousin through their common ancestor, Thomas Creekmore McCurry.

Roberts came to Washington to work on the staff of Republican Kansas Sen. Frank Carlson in 1967. He was first elected to the House of Representatives in 1980 and won his Senate seat in 1996.
