I generally vote for third party candidates. In the 2016 race only 58% of eligible voters went to the poll. The candidates see the suppressed vote as a success.

The third party vote was only about 4%. In this last election the third party vote was high enough so that neither candidate got more than 50% of the vote.

Imagine if a large portion of the people who stayed home went to the polls and voted third party: The political class would have freaked out even more than it did with Trump's winning.

A large third party vote shows that people are getting tired of the kleptocracy of the ruling class. The third party vote is the thing that the big parties fear.
