That's one option. Another option is to reject that either major party offers a sane choice and vote for a third party.

Unless the election already has an obvious winner so your vote doesn’t matter, that’s just silly. Write an editorial if you’re unhappy with the choice, but don’t throw away your vote and just roll the dice as if you’re indifferent to the two alternatives. (And if you really were indifferent to the alternatives this time around, I don’t know what to say.)
