Topeka ? A former Kansas attorney general says he’s running for the U.S. Senate because of concerns about federal spending.

Robert Londerholm Sr., now an Olathe attorney, said Monday that he intends to be — in his words — a little bit of a gadfly about fiscal issues.

Londerholm says he’s running because he’s worried his grandchildren will be saddled with paying off enormous federal debts.

Congressmen Jerry Moran and Todd Tiahrt already are seeking the Republican nomination. The only declared Democratic candidate is Charles Schollenberger, former newspaper reporter and editor from Prairie Village.

The 78-year-old Londerholm served as attorney general from 1965 to 1969, and he was later chairman of the Kansas racing commission.
