Answer:
was largely blocked by conservatives in Congress.
Step-by-step explanation:
J.F Kennedy's legislative programs were largely blocked by conservatives in Congress. Some of his initiatives that encountered failure were federal aid education, aid to areas that experienced economic depressions and also provision of medical care for the aged.
The blockages he encountered all came from the conservative coalition of both Northern Republicans and Southern Democrats. Kennedy lacked congressional support for his legislative programs. He encountered resistance in Congress.
