What distinguished president eisenhower’s “modern republicanism” from his party’s policies in the past?

The Modern Republicanism was President Dwight's philosophy that sought to balance government intervention with individual freedom. His ideals were a response to more extreme Republicans whose argument was that Truman's Fair Deal and Roosevelt's New Deal should be whipped out. The reason being both of them had increased the government's spending.
Dwight's approach was moderate, as he tried to maintain some of the Truman's and Roosevelt ideals while allowing freedom of the individual and of the market.
