I dont understand why more United States citizens aren't voting for the underdogs. In the last election, it was possible for the greens to "win" . If you want to protest, instead of not voting, vote for the least likely to win. It makes a statistical analysis of the "protest votes" possible.. Under some (eg, normal curves) statistical models, you assume that the non-sampled closely resemble the sampled (with some level of confidence). By not voting you're basically saying "dont worry, I am very much like the 'norm'" . By voting for the underdog you're helping to elucidate the fact that you are not represented by the main parties.
