This day in history: RFK shot

June 5, 1968, Robert Kennedy was shot:

Senator Robert Kennedy is shot at the Ambassador Hotel in Los Angeles after winning the California presidential primary. 

Immediately after he announced to his cheering supporters that the country was ready to end its fractious divisions, Kennedy was shot several times by 22-year-old Palestinian Sirhan Sirhan. He was pronounced dead a day later, on June 6, 1968.

The summer of 1968 was a tempestuous time in American history. Both the Vietnam War and the anti-war movement were peaking. 

Martin Luther King, Jr. had been assassinated in the spring, igniting riots across the country. In the face of this unrest, President Lyndon B. Johnson decided not to seek a second term in the upcoming presidential election. Robert Kennedy, John’s younger brother and former U.S. Attorney General, stepped into this breach and experienced a groundswell of support...

Rob's comment:

Both JFK and RFK had to die before Richard Nixon could become president. He was elected in November, 1968, after a campaign based on the racist Southern Strategy.

The US attack on and invasion of Vietnam was not in fact "peaking" in 1968. It continued for another seven years thanks to Richard Nixon and the Republican Party.
