Johnson hasn't bothered to prepare because he knows he hasn't a hope in hell of getting elected, he isn't serious and is doing this as a lark. It's a fact that there is no serious third party candidate and there's a simple reason for this situation. There is no third party  capable of governing. It doesn't exist. You can count on one hand the number of third party pols holding any kind of high office. Unless this were to change significantly in some distant future, might as well vote for Donald Duck than a third party presidential candidate.
