Not voting and doing nothing is a great way to support the status quo.
There are tons of third-party candidates, many of whom are on the ballot in most states. If someone doesn’t like either of the major party candidates, it sends a much stronger message to vote 3rd party rather than not vote.
On top of that, in California and San Diego there are always a lot of dumb propositions on the ballot to vote no to. (Can we do away with the proposition system yet, or at least reform it?). There’s always at least one that is close to a 50-50 split, so even if your vote doesn’t seem to count on the Presidential election, there are other issues it does matter.
