The only things your hero Nixon did for the environment were for craven political reasons, when he knew he had no choice.
Nixon's responsiveness to various constituencies may have been as much a reflection of his political savvy as a commitment to New Federalism. Prior to the Earth Day demonstrations of 1970, the president showed little interest in environmental issues. But in the millions who gathered in communities around the nation, he saw political power.
The president sent dozens of environmental proposals to Congress, including the Clean Air Act of 1970, perhaps one of the most significant pieces of environmental legislation ever passed. He also created two new agencies, the Department of Natural Resources and the Environmental Protection Agency, to oversee environmental matters.
While Nixon increased spending on domestic initiatives during his presidency, he consistently stood by the New Federalist principle of fiscal efficiency. Nixon insisted that all environmental proposals meet the cost-benefit standards of the Office of Management and Budget. In 1972, he vetoed the Clean Water Act, which he generally supported, because Congress had boosted its cost to $18 billion. When Congress overrode his veto, he used his presidential powers to impound half of the money.
