Tonight, boys and girls, I shall explain - in terms anyone, no matter from which country , should be able to understand - why voting for the "lesser evil" is not just mindless idiocy, but is a clear trap:
Let's take this sequence, in which A is (by conventional standards) the least evil and Z represents the maximum evil:
We have, or pretend to ourselves that we have, two options to vote for: X and Y. Let's say X says his policy is A and Y says his policy is B. As the lesser of the two evils, you vote for X, who says he stands for A. Once in power, X actually gives you, in the manner of politicians, C, but you persuade yourself that Y would've given you D, so you were right in voting for X. So next time round, X offers E, Y offers F, and you vote for X because E is better than F. This time X gives you G, while Y foams at the mouth yelling about how without H the world will end. So you of course vote for X again. Right?
Perhaps, along the way, a third potential option appears – someone, let’s call him σ, who loudly reminds everyone that the original choice was between A and B, and you are now getting to choose between P and Q. σ promises to go back to A if you elect him. Whether he’s sincere or not, you’ll reject him without second thought, because you’ve convinced yourself that the choice is between X and Y. In fact, not only will you reject σ, you’ll be furious at him for potentially reducing crucial support from X, without which Y might win.
Suppose, despite all, it looks like σ will actually get substantial support. All X has to do at this stage is throw a few sops around, perhaps even retreat from P to O1/2, and you’ll go right back to voting for him – because he’s the better option than Y, dammit. As for σ, he’s thrown by the wayside, forgotten forever.
And this is the way it continues until you find yourself voting for X, who now stands for W, so as not to have Y, who promises Z.
Am I clear? In order not to have B, you've just ended up voting for W. Because you chose the "lesser evil" instead of using your brains.
Obviously, in this situation, X and Y will be working together – because their agenda is precisely the same, which is to steer you directly towards Z from A. And since you do exactly as they want you to, they both win and you lose.
And you will continue to lose as long as you refuse to use common sense.
That is your lesson for tonight.
