The 2016 election will most certainly not hinge on your decision to vote for this or that candidate or any other ballot issue. For example, even if we simplify that we have an Electoral College and you do not directly vote for a candidate, the probability that your specific vote will sway a mass election is approximately zero. The only time your vote has a consequence is if your candidate loses by one vote or is tied, otherwise it will win/lose regardless of your decision to vote.
Others emphatically argue that the individual's vote matters.
If your vote did not count why would politicians try to suppress it? Why would stakeholders and legislatures nationwide introduce policies to make it difficult for your voice to be heard by the casting of your ballot? And why would states across the country, from the period of American slavery to present, pass measures to make it harder for U.S. citizens — particularly black people, women, the elderly, students and people with disabilities — to exercise their fundamental right to cast a ballot? Why, in the early founding of this nation, would only property-owning, white men be allowed to vote?
