Answer: Caution toward civil rights legislation
Explanation:
John F. Kennedy had during his Presidential run, remained a steadfast supporter of Civil rights for the African Americans and showed this with his efforts to get Martin Luther King released from custody after he had been arrested following a protest. This act perhaps was the cherry on top that won him the African American vote.
This was not however welcome by all in his party. As a result of his stance on Civil Rights, members of the Democratic party in the South did not support him as much as they should have, if they did at all and this led to one of the closest popular votes in history.
Kennedy's administration knew then that it needed the support of Southern Democrats to be reelected as well as in congress to pass certain bills. He therefore tried not to antagonize them by limiting civil rights legislation.
This is not to say that he did nothing in the fight for civil rights though. He dispatched the US army to help enrol an African American named James Meredith in the University of Mississippi as well as introducing what would later become the 1964 Civil Rights bill that was passed after his unfortunate demise.
