Failed to provide relief on a National Level.

Explanation:

The Republicans clearly opposed the New Deal since it didn't provide a breathe of relief neither to those who have lost everything and didn't provide enough relief or to the government to stop worrying about the people.

During the 1930s, Republicans opposed the New Deal because it expanded the power of the federal government.

Explanation:

As FDR made sweeping changes to the structure of America's economic system amid the Great Depression, Republicans often declared that Franklin Delano Roosevelt's expansion of government power to propel the economic recovery was socialist and communist. From the 1930s to now, the Republican Party has maintained its economic stance as supportive of laissez-faire capitalism and reproachful towards any social policy that expands government spending such as universal healthcare, pensions, and universal child care. Although the Republican Party is still supportive of laissez-faire capitalism, the economic system's lack of regulations were attributing causes to the Great Depression.
