"It is thinking of the next campaign – the desire to be re-elected – that provides the second pressure on the conscientious Senator... Defeat, moreover, is not only a setback for the Senator himself – he is also obligated to consider the effect upon the party he supports, upon the friends and supporters who have “gone out on a limb” for him or invested their savings in his career, and even upon the wife and children whose happiness and security – often depending at least in part upon his success in office – may mean more to him than anything else. Where else, in a non-totalitarian country, but in the political profession is the individual expected to sacrifice all – including his own career – for the national good? ... Lawyers, businessmen, teachers, doctors, all face difficult personal decisions involving their integrity – but few, if any, face them in the glare of the spotlight as do those in public office. Few, if any, face the same dread finality of decision that confronts a Senator facing an important call of the roll. He [Senator] may want more time for his decision – he may believe there is something to be said for both sides – he may feel that a slight amendment could remove all difficulties – but when that roll is called he cannot hide, he cannot equivocate, he cannot delay, like the Raven in Poe’s poem, is perched there on his Senate desk, croaking “Nevermore” as he casts the vote that stakes his political future."
