lyndon R Inhnson

d. Richard M. Nixon

Explanation:

President Nixon is one of the most famous presidents of the United States with his popularity gained from being the only president to resign to his achievements in foreign policy which saw him remove the US from the Vietnam war as well as take important steps to peace with both the Soviet Union and China through Henry Kissenger.

Perhaps a lesser known but still a known fact nonetheless is his support for New Federalism which was a policy that would see more Federal power going back to the States and municipalities.

One way he showed his support for this policy was by backing a revenue sharing plan that would see the Federal Government give more funds to the states without restricting what they could use the money for which would therefore give the states more leeway to spend money received.
