It is clear that no third party has added to its organization or size in the last 3 years.

Therefore, all of us can predict with certainty that the next president of the United States will be either the Republican Candidate or the Democratic Candidate. We can say that with 99.99999% degree of certainty.

If that is the case, then why would anyone do anything to throw this election to the Democrats by either staying home or voting 3rd party?

Even in terms of 3rd parties my sense is that they would do better at elevating their visibility by ENDORSING one of the 2 main candidates rather than by running one of their own.

It is absolutely the case that we will have a president from one of the two major parties for many years to come. (Given that, it really doesn't matter who or what minor parties endorse.) Those who would vote 3rd party or stay home to "teach a lesson" are choosing a fools errand.
