Eisenhower then articulated his position as a moderate, progressive Republican: "I have just one purpose ... and that is to build up a strong progressive Republican Party in this country. If the right wing wants a fight, they are going to get it ... before I end up, either this Republican Party will reflect progressivism or I won't be with them anymore."
