Absolutely! Throwing away your voice because you're in a snit over the choices only gives the one you dislike most the chance to win. Only about 25% of eligible American voters actually decide who the president will be. So, every single vote counts.

The third evil: Not voting at all
Voting is a choice and a right, not some wonder device that makes one any more intelligent, nor any more American.
What you suggest is to ignore the often putrid choices handed to you, but you should choose one anyway. That doesn't even make bad sense. All you've done is play into the corporatist duopoly.
African-Americans don't vote for republicans for very good reasons. Thus, if the democrat running is unacceptable to black voters, the choices are vote 3rd party or don't vote at all.
If this country was serious about elections, it would remove the impediments to 3rd party growth and give voters real choices on who to support.
There is nothing stopping anybody from running a third party. The problem is any third party candidate running would be leaning to one side or the other. A vote for that candidate is a red carpet to the White House for the candidate that is opposite of their view.
If Sanders loses and decides to run a third party, that would guarantee a Trump win. If Trump gets upset with the Republicans and decides on a third party run, that guarantees a Hillary win.
That's just the way our politics is and it's not going to change in our lifetime. The best anybody can do is vote the worst person out.
In my opinion, and with all due respect, that's a ridiculous idea that only plays into the colonization of the American people. We are a colonized people who accept our roles as subjects to the Crown, not citizens .. mere observers to our fate.
Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.
People who play the game that you suggest are indeed subjects, not citizens. The best that can be hoped for is 'lesser evil.'
Rights in this country are not determined by what is just, right, fair, humane, honest, or by what Jesus would do. Rights in this country are determined by what you can demand .. and If you cannot demand those rights, they aren't your rights. That's the only way it works in America.
Until the American people stop acting like subjects and demand access to the ballot for 3rd parties, we deserve whatever government we get.
