While the rightward shift in the Republican Party started in the 1970s, Nixon like Dwight Eisenhower and Gerald Ford, largely governed in accordance with Keynesian modern liberal principles on domestic issues, especially fiscal policy.[64] As President, Nixon imposed wage and price controls,[65] indexed Social Security for inflation, and created Supplemental Security Income (SSI).
