Question

what stood in the way of president kennedys goals of sending a man to the moon, increasing federal spending for education, and increasing aid to relieve poverty?

unpopular tax increases
foreign crises that required attention
because of opposition from a majority of democrats
a potential federal budget deficit

Explanation:

During John F. Kennedy's presidency, his ambitious domestic and space goals (moon landing, education spending, anti-poverty aid) faced pushback due to concerns about growing federal spending leading to a budget deficit. Tax increases were proposed later under Johnson, foreign crises were not the primary barrier to these domestic/space goals, and Democrats generally supported his agenda, so those options are incorrect.

Answer:

a potential federal budget deficit
