The three main issues of the 1968 presidential campaign between Richard Nixon and Hubert Humphrey included all of the following EXCEPT

a. violence and disorder
b. the energy shortage
c. racial unrest
d. the war in vietnam
------------------------my answer: B?
vietnam war was still going on during the presidency of 1968 so President Nixon claimed to have a plan to end the war. Because of the Vietnam war, there was violence and disorder. Also, during that time, Martin Luther King got assassinated and he was the main black person who claimed for equal rights to the black people.

You're right! C is the best answer.

Yes, we didn't have our first wake-up call about energy shortages (if you can call it that) until 1974 or 1975. It wasn't even a concern in those days.

Your answer, B. the energy shortage, is correct.

To arrive at this answer, let's analyze each option:

a. Violence and disorder: This issue refers to the widespread protests and social unrest that occurred during the late 1960s, including the civil rights movement and the anti-war movement.

b. The energy shortage: This option is not one of the main issues of the 1968 presidential campaign between Nixon and Humphrey. While energy issues did become prominent during the 1970s, particularly with the OPEC oil embargo in 1973, it was not a central issue in the 1968 campaign.

c. Racial unrest: This issue refers to the ongoing civil rights movement and the struggle for racial equality. The assassination of Martin Luther King Jr. in April 1968 contributed to heightened racial tensions and protests across the country.

d. The war in Vietnam: This option refers to the ongoing Vietnam War, which was a major issue in the 1968 campaign. Nixon campaigned on a promise to end the war and bring about peace.

Therefore, the correct answer is b. the energy shortage.
