I find Johnson appealing and Libertarianism is not entirely my cup of tea, but it has some really good points.
And I dislike Trump enough to worry that if my vote helps him win , I will feel bad about it.
I am presently undecided.
The main reason I have for voting for Trump is the extreme wrongness of Hillary, he only looks good in juxtaposition to her.
I can easily imagine many potential Hillary voters considering her the "lesser" evil.
So a scheme that allows my vote to be attached to a vote that would have gone so wrong otherwise allows me to vote as I might really wish, freed from the fear and responsibility of the beloathed winning.
So Johnson is getting my attention, if I see enough good there I think I may vote for him.
I may also join the NRA, to improve Hillary's chances of loosing at the same time.
