The group of Americans Nixon assumed were turning against liberal programs was known as the

A.
Christian Coalition.

B.
Moral Majority.

C.
New Democrats.

D.
Silent Majority.

D. Silent Majority.

The correct answer is D. Silent Majority.

To find the answer to this question, we need to analyze the given options and their relevance to the context of American politics during Nixon's presidency.

A. Christian Coalition: The Christian Coalition is a conservative political organization founded in 1989, well after Nixon's presidency. It primarily focuses on promoting a Christian conservative agenda and political candidates.

B. Moral Majority: The Moral Majority was a political organization founded in 1979 by Jerry Falwell, a prominent evangelical minister. However, the Moral Majority emerged after Nixon's presidency, so it is unlikely that this is the correct answer.

C. New Democrats: The New Democrats refers to a group of center-left political figures within the Democratic Party. They gained prominence in the 1990s and advocated for policies that were more moderate and centrist. Therefore, this group is also not relevant to Nixon's presidency.

D. Silent Majority: The Silent Majority is the correct answer. This term was used by President Richard Nixon in a speech in 1969 to refer to the group of Americans who supported his policies but did not vocalize their opinions in public demonstrations or protests. Nixon believed that this group constituted the majority of the American population and that they were turning against liberal programs.

Therefore, the correct answer is D. Silent Majority.
