From H.L. Mencken’s essay, The Politician:
“AFTER damning politicians up hill and down dale for many years, as rogues and vagabonds, frauds and scoundrels, I sometimes suspect that, like everyone else, I often expect too much of them. Though faith and confidence are surely more or less foreign to my nature, I not infrequently find myself looking to them to be able, diligent, candid, and even honest. Plainly enough, that is too large an order, as anyone must realize who reflects upon the manner in which they reach public office. They seldom if ever get there by merit alone, at least in democratic states. Sometimes, to be sure, it happens, but only by a kind of miracle. They are chosen normally for quite different reasons, the chief of which is simply their power to impress and enchant the intellectually underprivileged. It is a talent like any other, and when it is exercised by a radio crooner, a movie actor or a bishop, it even takes on a certain austere and sorry respectability. But it is obviously not identical with a capacity for the intricate problems of statecraft.
Those problems demand for their solution—when they are soluble at all, which is not often—a high degree of technical proficiency, and with it there should go an adamantine kind of integrity, for the temptations of a public official are almost as cruel as those of a glamor girl or a dipsomaniac. But we train a man for facing them, not by locking him up in a monastery and stuffing him with wisdom and virtue, but by turning him loose on the stump. If he is a smart and enterprising fellow, which he usually is, he quickly discovers there that hooey pleases the boobs a great deal more than sense. Indeed, he finds that sense really disquiets and alarms them—that it makes them, at best, intolerably uncomfortable, just as a tight collar makes them uncomfortable, or a speck of dust in the eye, or the thought of Hell. The truth, to the overwhelming majority of mankind, is indistinguishable from a headache. After trying a few shots of it on his customers, the larval statesman concludes sadly that it must hurt them, and after that he taps a more humane keg, and in a little while the whole audience is singing “Glory, glory, hallelujah,” and when the returns come in the candidate is on his way to the White House.”
