I've never heard that Eisenhower was a cheater. What's the story there?
As Higgins said above, there is a long-standing story that Eisenhower had an affair with his chauffeur Kay Summersby while he was in Europe for the war, and Summersby herself claimed that it happened, but many people who knew both of them said that they thought it was unlikely. It's never really been totally proven one way or another if they actually had sex, although they were effectively living together for years and were very close.
