I think those who don't vote don't vote because they either don't know anything about the candidates or they don't support any of the candidates. This is however a terrible reason not to vote. To show this to you let me tell you a story.

I worked for a campaign once. This campaign was very small so I had much more responsibility than I deserved. The first thing I was tasked with doing was going to city hall paying $25 and getting a copy of all voter data. I was shocked that this list existed and I don't think most people know this. It is a list of all registered voters: Their address, name, sex, party affiliation, birth date and most importantly whether or not they voted in each election for the past 20 years. It doesn't say who you voted for just whether or not you showed up at the polls. The next thing I had to do was analyze that data. I put it in excel, broke it up by common demographic groups and scored each issue by it's demographic support according to polling data and how likely those groups were to vote on that issue. It turned out that (not surprisingly) In pretty much all cases we would be fools not to do exactly what the 65+ group wanted solely because they voted in every fucking election. Even the elections for school council. And they don't even have kids in school. (well maybe grand-kids)

So the only way for you to have candidates that actually support your view is to show up at the polls. But you don't even actually have to vote. Just go to the polls. When you enter they will mark off that you have voted and give you a ballot. You then proceed directly to the ballot drop off with an empty ballot. You have not voted but it looks like you did and you will show up on the list. Now next election due to the fact that you at least got off your ass and got to the polls you are more likely to have a candidate that you WILL want to vote for.

For those of you who do vote already remember this argument and tell it to others. I have never heard anyone make this argument in trying to convince people to vote but to me it seems like the best reason of all to vote. That list that shows whether or not you voted is the most powerful thing in this country. It is your declaration to those in power that you exist and you matter. If you don't show up there you are meaningless.

TLDR If you don't want to vote for any candidate go to the polls and turn in an empty ballot. Your name address and age are recorded and next year the politicians will be more likely to court your vote. Meaning next year you may actually have a candidate you like.
