We were told that Gary Johnson was doing a Town Hall on his campaign website, but we missed it. From the comments on the Johnson campaign’s Google Plus profile, it looks like there were technical difficulties anyway.
The video may be posted at some point on the Gary Johnson Youtube Channel. If anyone has any updates on this, please post a comment.

Ron Nielson seemed to indicate yes, in the conference call with the LNC

I took some notes from watching the first hour or so of the webcast.
Technical difficulties also prevented me from viewing it.
I wasn’t able to view the town hall due to technical difficulties.
I’m also wondering whether he said anything about the 2016 presidential nomination.
Did he say whether he will seek the 2016 LP nomination?
