a. he promised to end the vietnam war.
b. he belonged to the same political party as johnson.
c. he had political views and strategies that were liberal.
d. he had served as johnson’s vice president.

The correct answer is A) He promised to end the Vietnam War.

Lyndon B. Johnson was a Democrat and Nixon was a Republican conservative. This shows that letter choices B and C are incorrect.

Hubert Humphrey served as Lyndon B. Johnson's Vice President during this time, showing that letter choice D is incorrect.

This shows that the only correct answer can be A. Despite the promise that helped propel him to victory, Nixon had the US involved for several years after he was elected.
