Explanation:

The Rockefeller Republicans, also called Moderate or Liberal Republicans, were members of the Republican Party (GOP) in the 1930s–1970s who held moderate to liberal views on domestic issues, similar to those of Nelson Rockefeller, Governor of New York (1959–1973) and Vice President of the United States (1974–1977).

Most moderate Republicans in Congress supported the president's proposal for Reconstruction because they wanted to bring a swift end to the war, but other Republicans feared that the planter aristocracy would be restored and the blacks would be forced back into slavery.
