So, At The End Of The Day,

In 4 years I have no doubt that the myth of viable 3d parties will be resurrected.....

You say that as if that was a negative. Given your political system it probably is, but that rather shines a light on your political system than third parties. The problem lies in not giving third parties a voice, not in third parties existing. Just think about it. For more than 200 years two political parties are dividing the country amongst them. But at the same time, people get more and more diverse.
