Well, that was when political leaders still had a shred of integrity.
He was certainly public-minded and tried to serve his country well. He enforced desegregation and ended the Korean War.
But he also oversaw the creation of the military industrial complex, which he would famously (if somewhat ironically) lament in his farewell address. And that's arguably where America's current problems with money in politics started.
The rise of the CIA and its support of antidemocratic regimes is also part of Eisenhower's legacy. Operations TPAJAX and TPSUCCESS were done with his close support and involvement. He also sponsored the government of Ngo Dinh Diem in South Vietnam which refused to implement the 1956 Geneva Accords, leading to the disaster of the Vietnam War.
Overall, he cemented the turn away from New Deal era social democratic policies that had already begun in the Truman years as the Red Scare was finally taking hold of the United States.
