Scratch a Libertarian, find a Liberal.
Johnson should not be part of the debates. He will side with Hillary. I guarantee it.
I'm undecided on what would be best for us strategically. The Democrats and a good portion of the GOP establishment think that promoting Johnson will guarantee the Hillary victory that they want, but I suspect they'll be in for an unexpected surprise. A lot of Democrats for whom social issues are more important than their love of high taxes and big government may vote for Johnson.
