In 1952 a constellation of racist and anti-semitic far right groups, calling themselves "Nationalists," gathered before the GOP convention in Chicago with the hopes of getting their man, General MacArthur, nominated. They thought Eisenhower was a RINO.
"So much hate material was passed out around the convention hotels that a majority of all pro-MacArthur stuff originated among the Nationalists. They pushed aggressively into the Republican convention structure and made themselves very much at home."
"Approximately 200 delegates from various & #39;patriotic& #39; groups gathered to plan strategy for the big convention. A rift was caused by the question of how much overt anti-Semitism should be used and it was this disagreement which caused the Nationalists to split into two factions."
