How successful were President Kennedy’s domestic policies?

Despite lasting only 1036 days, many historians have argued that Kennedy’s domestic policies achieved much success in that they were wide ranging and ambitious. With policies such as Medicare and legislation designed to protect workers and stimulate the economy, Kennedy seemed to be fulfilling his optimistic promises of his campaign. However, such policies were often more successful in writing than it practice, particularly given that foreign policy issues as a result of the ongoing Cold War (such as The Cuban Missle Crisis and Berlin Wall) dominated his time and so this would perhaps undermine the success of his policies as a whole.
