The Johnson administration focused on civil rights and social welfare programs, while the Nixon administration focused on environmental protection and a political strategy to appeal to Southern voters. From this information, it can be concluded that the Johnson administration was more liberal than the Nixon administration and that both presidents had different policy priorities. It cannot be concluded that unpopular policies prevented either president from completing their terms or that one president's policies were more effective than the other. Additionally, there is no information provided to suggest that either president acted without congressional approval to pass laws.
