Walking his son to school, past the all-white school to Slowe Elementary School in
Northeast, Washington, D.C., gave Hobson the drive to fight for school desegregation. The court ruled in his favor, banning discrimination in the
District of Columbia Public Schools and stopping its system of grouping students by ability on June 19, 1967. He decided to run again for a seat representing Ward 2 the next year, but he lost the race to Evie Mae Washington. In an effort to protest the employment discrimination practiced by
Pepco, Hobson distributed stamps that were intended to be pasted on check payments sent to Pepco that would prevent Pepco's computers from processing the checks. He was later ordered by court to stop distributing the stamps. He lost to Democrat
Walter E. Fauntroy. Hobson was elected in 1974 as one of the at-large members of the
Council of the District of Columbia at its creation, and he served in that position until his death in 1977. In a 1972 interview, Hobson said one contemporary he admired was
Sterling Tucker, not because he agreed with him on everything, but because he was smart and cunning, worked with everyone, and had many political accomplishments. ==FBI Informant==
