I voted for Gary Johnson. But I do understand the votes for Trump.

However, you might want to reconsider in the future. Not voting for the libertarian candidate because you believe they "have no chance of winning" is not really helping the cause btw.

I.E., if no one votes for the third party for fear of losing, then a negative feedback loop is constantly reinforced every 4 years and thus the Libertarian party's chances of winning will never grow, because their percentage of overall votes will never grow.

Despite this behavior, though, the Lib party's percentage of votes is growing. The near term goal is to gain enough %  of the votes to where the Lib party can no longer be ignored by the establishment.
