Right. A missing vote could be anywhere on a spectrum from "these both suck so bad that I can't bear to vote for either" through "things are great, I think either candidate is fine, and I trust my fellow Americans to make the right call", plus a chance of laziness. A vote for a third party is clearly a vote not for either major party candidate.
