The absolute worst analogy I’ve heard in my entire life (that includes personal, professional and academic).
An astute observer (that pretty much rules you out) would have noticed that Sanders was the only candidate to explicitly state that voting for the “right” people is less than half of the battle. Meaning, he openly acknowledged that the two-party system is a complete sham, and the public en masse needs to effect social change through social activism. Of course, the sods will keep believing there is a difference between the two major parties, and keep waiting for politicians to enact legislation that will save the middle-class. The only true winners will be the capitalist class, the people who work for the capitalist class (i.e. politicians) and the national media that makes millions (billions?) of dollars covering the two-party system - sad.
