All these influences will result in a person voting for one of, say, three parties. Each vote may seam to have very little effect on the whole result but a single vote could give one party the lead over the other. If this happens there is no way to really trace which vote it was, but one voter changing his mind could result in a coalition or a single party ruling the country. Because each voter votes for a reason, general elections are not random, just unpredictable. This, to varying level of complexity, is true for all chaotic systems.
Chaos theory is about patterns.
Because a chaotic system is about repeated steps often irregular patterns, or sometimes almost regular patterns are produces. One example of this is the Mandelbrot set. This is a pattern produced by a simple function that is infinite in detail but, quite clearly include many patterns that repeat themselves in constantly changing ways. Some patterns will reoccur at different intervals and stay relatively stable for some time. These are called attractors, sometimes called chaotic attractors or strange attractors.
