Refusing to accept the facts of any given situation is always a fool's errand.
Forinstance, when one is in a romantic relationship in with an unfaithful partner and chooses to ignore the warning signs of infidelity, the short-term pain averted will be almost inconsequential compared to what will be experienced from the turmoil which lays ahead. The same is true for a voter who remains supportive of a longtime public officeholder known to be on the take. When reality hits you in the face, it can be tempting to turn the other cheek, but, as I said above, ultimately a fool's errand.
The political process, needless to say, is no place for fools. Yes, many do participate in it, and some have even reached its highest levels in the past, but never really attained any great degree of power. A prominent example of this would be the late Warren G. Harding, a man who was thought by even the closest of his friends to be not the brightest of bulbs, so to speak. Despite rising from the position of country newspaperman, and not a very successful one at that, to president of the United States in a relatively short period of time, he was controlled by his manipulating handlers every step of the way. Quickly after his inauguration, he appointed most of his comrades, whom he thought to be genuinely good people, to every cabinet and administrative post available. Nearly all of these people would go on to be engaged in corruption of such a magnitude that, had Watergate taken place back then during the early 1920s, it would have been last page news in a small handful of alternative weeklies. Eventually, Congress became aware of all that was going on and made noises about impeaching Harding, who was caught like a deer in the headlights and had profited absolutely nothing from his appointees' dealings. Unexpectedly, he died one day while touring San Francisco, due to causes which still remain unknown — though most historians believe that his doting wife poisoned him in order to save his dwindling reputation and status as a free man.
