I chose that memorable Saturday Night Live bit above because it shows Jesse Jackson, the civil rights leader who died today, at his best: smart, self-deprecating, charming and likeable. Jackson could slide into demagoguery (he was good at it), and he was frequently, even usually, a divisive presence on the national scene. Nonetheless, he was ultimately a catalyst for more good developments in American society, culture and politics than bad. But it’s a close call.

Civil rights was by no means achieved by the time Martin Luther King was assassinated in 1968. The stain of Jim Crow was still strong in the South, and de facto segregation was rife everywhere else, as in my hometown of Boston where it often seemed like there were more black players on the field playing for the Red Sox than in the stands at Fenway Park. The school busing controversy was six years away in 1968.

With the eloquent and charismatic King martyred, the nation needed a new leader of the civil rights movement. Malcolm X was brilliant and charismatic but radical and racist. Rev. Ralph Abernathy was boring, a pale (no pun intended) successor to King. The other leaders of the civil rights movement resonated as grifters, determined to prove Eric Hoffer right when he argued that “Every great cause begins as a movement, becomes a business, and turns into a racket.” As happens so often in American history, Jesse Jackson was the right leader to emerge when the nation needed him.
