And if all 4 candidates are people you don't want making decisions about your life?
I could have just as easily created another 2 candidates in my blog who were also unseemly.
Your argument seems to be "This system is awful, but its going to remain awful, so you may as well put your statistically insignificant vote in the box in the hope that the least awful person may win...which of course legitimises the awful system we have"
...Or am I missing something?
