How did you get these numbers? I would have thought that if your V was 0.1, your delta would be 672. If my understanding is correct, your've underestimated the effect by about 2, and the crossover V is around .15. Do I misunderstand your model? I actually have an opinion on the likelihood of

Surely some voters would choose to leave the ballot blank. If I didn't like any of the presidential candidates, but I thought that some more local election was worth voting in, I might do that. In fact, in the local municipal election that we just had, I was allowed to vote for as many as 4

As I said the model is very simple. It could be complicated by allowing for no votes at all, thus one has 28000(0.62V+0.5W), where V+W1. This would make the resulting deltas smaller, but require the input of an additional unknown parameter. The point that I intended to suggest is that everyone

In addition to being unable to spell "fallacy," I can't do arithmetic. Chung is right. The formula is 28000*0.24*V, which is 672 for V=0.1. It might be better to add a multiplicative parameter to remove from the 28000 the genuine "no vote" totals. Thus one has 28000*H*0.24*V, from which one can
