Yes! But not sure what your point is. JFK's agenda was heavily influenced by the views of the Academic Left, as witness those whom he appointed in key positions to deal with the rest of the world, starting with his Leftist Secretary of State, Dean Rusk, who did more damage in the Third World, from the standpoint of Western interests, than the Soviet Comintern, itself!
JFK got 43% of the Protestant vote, which was slightly BETTER than the Democrats had done in a few elections. With no JFK there would have not Kennedy empire or Johnson, or Vietnam, or the 1960s, it was the election which destroyed us.
However, if there is one man who can take the most credit for the 1965 act, it is John F. Kennedy. Kennedy seems to have inherited the resentment his father Joseph felt as an outsider in Bostons WASP aristocracy. He voted against the McCarran-Walter Act of 1952, and supported various refugee acts throughout the 1950s. In 1958 he wrote a book, A Nation of Immigrants, which attacked the quota system as illogical and without purpose, and the book served as Kennedys blueprint for immigration reform after he became president in 1960. In the summer of 1963, Kennedy sent Congress a proposal calling for the elimination of the national origins quota system. He wanted immigrants admitted on the basis of family reunification and needed skills, without regard to national origin. After his assassination in November, his brother Robert took up the cause of immigration reform, calling it JFKs legacy. In the forward to a revised edition of A Nation of Immigrants, issued in 1964 to gain support for the new law, he wrote, I know of no cause which President Kennedy championed more warmly than the improvement of our immigration policies. Sold as a memorial to JFK, there was very little opposition to what became known as the Immigration Act of 1965.
