He's still better than either of those two.
But I agree, he should dump the TPP.
I will be honest with you. If he dropped the TPP and did not give implicit support of Hillary and explicit hate to Trump I would possibly warm to him a bit more. It has to be a shit position, to know you have not a hope in HELL even getting 15% of the vote. The Libertarian Parties policies are not terrible. They are just so small.
I think if you could have a bowlful of the Libertarian Party and a couple of healthy dollops of Republican policies and a couple of tablespoons of Green Party Progressivism and mix it up, you'd get a pretty good policies.
