How did President Johnson's view of the Great Society program change in 1968?

He realized that he should never have started the Vietnam War and he was very disappointed with his 1966 decision of starting the war.
He realized that the federal government should have only a limited role in society, not the strong role the Great Society program required.
He realized it was the role of states, not the federal government, to financially help struggling Americans.
He realized that the issues the Great Society program faced could not be resolved in such a short time frame.

There is no definitive answer to this question as President Johnson's views on the Great Society program evolved over time and were influenced by a variety of factors. However, it is worth noting that by 1968, Johnson was facing mounting criticism and challenges both domestically and internationally, including the escalating conflict in Vietnam. As a result, he may have become more skeptical of the feasibility and effectiveness of the Great Society program in achieving its goals. Additionally, with the country increasingly divided over issues such as civil rights and poverty, Johnson may have recognized the limitations of federal government intervention in solving these complex social problems. Ultimately, Johnson's changing views on the Great Society program in 1968 likely reflected the broader political and social challenges facing the country at that time.
