Robert Cohen and I met 45 years ago when we were both graduate students at Yale. I remember well our political discussions in the spring of 1948 during the race for the presidency among Truman, Dewey and Wallace. Bob and I were united in our opposition to Dewey, but divided over who might successfully challenge him. He supported Wallace while I supported Truman, arguing that a vote for Wallace was in effect a vote for Dewey. At that time, I did not know enough of the lingo to use my strongest argument against Bob — to dismiss his position as one of utopian idealism.
