I think the only way this idea gets off the ground is if Mr. Gray says publicly (with Gov. Johnson's and the LNC's assent of of course) that he is willing to step aside and publicly ask Paul to consider joining the ticket. Anything else would look like he was trying to muscle his way onto the ticket.
I find it amazing RP simply cannot give a definite yes or no answer to any question. By not saying he absolutely rules out any such non-major party bid he encourages sincere people like this fellow in Alaska who are not willing to see the campaign come to an end say "so you're saying there's still a chance right?" Sometimes he brings his own problems on himself.
Of course Rand has probably gotten wind of this by now (news never stays hidden around here) and I guarantee you he's going to make sure RP doesn't announce anything newsworthy on Leno this Tuesday.
Sounds like the last 3 months. Ron Paul Campaign sends out an email with not enough delegates to win. Everyone attacks Benton instead of realizing what it means. I'm there too, explaining what a Black Swan event was and how it could effect things.
Ron isn't going to cut off his options. So don't expect him to. A Johnson / Paul ticket on the LP is more feasible than Ron Paul as an I. I can see the first one, not the 2nd. Unless some Mark Cuban type steps up into the VP spot with Ron Paul. The money just isn't there otherwise.
