Questions: The second wave of government regulatory power after the New Deal came under this president's administration.

The answer is Nixon.

The second wave of government regulatory power, often referred to as the "regulatory revolution," occurred during the Nixon administration. This period saw the establishment of several key regulatory agencies and environmental laws, such as the Environmental Protection Agency (EPA) in 1970 and the Clean Air Act amendments. These initiatives marked a significant expansion of federal regulatory power.

While the Clinton administration did see some regulatory changes, particularly in areas like telecommunications and financial services, it is not typically associated with a major wave of new regulatory power akin to the New Deal or the Nixon era.

The Kennedy administration focused on various domestic issues, including civil rights and economic policies, but it did not initiate a significant wave of new regulatory power comparable to the New Deal or the Nixon administration.

Lyndon Johnson's administration is best known for the Great Society programs, which focused on civil rights, poverty, and education. While these programs expanded the role of government, they did not primarily focus on regulatory power in the same way as the Nixon administration's environmental and consumer protection initiatives.
