Assume a person voted third party because they can't stomach Trump or Clinton. But, that person favors stricter immigration enforcement, tax cuts, reduced government regulation, and other things Trump favors. To that voter, Trump winning comes closer to some of the policies they favor than had Clinton won.
I have heard people argue that with a Republican Congress Clinton could pass little of her platform and even with a Republican Congress Trump is not going to get most of his proposals passed. Therefore, government would accomplish little under either president which is preferable to any of the policies either proposed.
I think this thread is more of an argument that you think Clinton's policies are preferable to those of Trump, not whether 3rd party voters can justify their votes. Some posters did answer your challenge about the ten issues, you just do not agree with their policy choices.
The problem Trump is running into with fellow Republicans is they didn't get one of their own insiders and would rather lose politically than work with the guy that represents their party so they take their ball and go home.
