When the political scientist attempts to assess the state of civil liberties in America following World War II, he confronts a voluminous record of episodes and events. Most of the books, articles, and other documents so far available suggest that the fear of communist subversion carried Americans very far from the spirit, if not the letter, of the Bill of Rights. Indeed, it is possible to conclude that the hysteria associated with the name of Joseph R. McCarthy permeated almost every state, city and hamlet in America, and that McCarthy himself, in the words of Richard H. Rovere, “held two Presidents captive, or as nearly captive as any Presidents of the United States have ever been held …” The political scientist may therefore be persuaded that the label McCarthy Era better fits the Nineteen Fifties than the alternative designation, Eisenhower Era.
It may be hoped, however, that his research will not overlook those incidents, however rare, which suggest that fear and suspicion did not entirely dominate the national scene. One such incident, of more than ordinary interest, occurred in Iowa during the early months of 1951. By April, 1951, more than one year had elapsed since the late junior Senator from Wisconsin had produced his famous if elusive “list” of card-carrying communists in the State Department. The Korean War, moving toward the end of its first winter, promoted a mood which was, on the whole, favorable to the Senator's activities. Nevertheless, in April, 1951, the Iowa Senate overwhelmingly rejected a loyalty oath measure which was much less stringent than those that had previously been approved in almost half the states. The action of the Iowa Senate, moreover, was not merely unusual or exceptional in 1951; it appears to be without precedent in recent history. So far as is known, Iowa was the only state in which a loyalty oath measure was defeated by vote in the legislature.
