The answer is letter c Hubert Humphreys. Nixon made the decision to run for president
again in 1967. He believed he had a better chance due to the effect that
Vietnam War had on the Democratic Party.
Still he expected that it would be close election. Factors that increased his chances of winning
were the announcement of President Lyndon Johnson of not seeking another term
and the assassination of Robert Kennedy.
He also appealed to conservative Americans who disliked the
counter-culture of the hippie movement.
He won a three-way race between Humphreys and George Wallace for the
Presidency and was sworn in on January 20, 1969.
