The Willis Smith campaign of 1950 was a prime example of this movement.
Most important, Graham had served on Truman's Presidential Commission on Civil Rights, which sparked the Dixiecrat revolt in the first place.
On one side, liberals like Truman, Graham & Gov. Kerr Scott, who'd appointed him to the seat.
On the other, conservative Willis Smith ... and a young strategist named Jesse Helms.

He gained fame as an editorialist on WRAL-TV, where he fought the civil rights movement. (Text from @Lankwa's great Helms bio.)
