Yes, I’ve heard of him. This is the second time he has run for president on the Libertarian ticket, and before that he was the (Republican) governor of New Mexico. My opinion of him is that he’s closer to actually being a libertarian than some of the party’s previous nominees, but he’s still better characterized as a Republican who thinks we should be allowed to smoke pot. He’s too invested in the private prison industry to be as concerned with civil liberties as he says he is (much like Ron Paul is too concerned with what happens in people’s bedrooms and doctor’s offices to be considered a proper civil libertarian).
