Well, scm, you beat me to it. I was just going to post this about Jacob Hornberger and his campaign, so I will post it now.
Jacob Hornberger has been around in the libertarian world for decades. He is not 100% voluntaryist, but that's okay. He is extremely principled, especially when it comes to the non-aggression principle as applied to voluntary exchange, free markets, private private property rights and freedom of association.
And also when it comes to foreign policy: close down ALL foreign U.S. military bases and bring ALL the "troops" back to the U.S. They don't belong on those other territories! Stop invading, bombing and occupying other countries, period!
And he advocates peaceful trade and voluntary contracts on the immigration issue as well. The unalienable rights of each individual, especially to life, liberty and the pursuit of happiness, preexist the formation of any government, and preexist the formation of any country as well.
And a part of that whole immigration controversy is the drug war. Jacob understands and expresses the problems that drug prohibition causes. Drug prohibition causes a black market which gives us drug pushers and drug traffickers, drug lords and turf wars, and violence that many of those South and Central American immigrants are fleeing from. Another problem that Jacob has addressed is the problem of foreign aid, which ends up in the hands of those corrupt regimes in Honduras, El Salvador, etc, from which the people there are fleeing as well. End the drug war, end foreign aid, and you'll resolve much of the problem with "illegal" immigrants.
After all, why must individuals have to get the government's "authorization" to get a job somewhere or to hire someone in a free society? And who made the government the boss over what we may or may not ingest in our own bodies?
Ending the welfare state would also help. One problem with so-called libertarians like Gary Johnson is their acceptance of income confiscation and redistribution, such as the income tax and Social Security and Medicare. Jacob Hornberger rejects those things.
I think Jacob can add something that's been missing in these Libertarian Party campaigns for decades now since the 1988 Ron Paul campaign, a real understanding in terms of economics, philosophy and history of the principles of freedom and free markets.
