He needs to explain that CFL is about ideas, not a person, and that while the roles of leader and face of the campaign do fall to him, it must be about more.
He definitely needs to emphasize that people shouldn't vote for him, as he has said that in some states such votes won't even count.
He needs to pick Baldwin or Barr, to unite his following. However many votes it will be, they will be more impressive as a block for one candidate than split between two similar candidates. It doesn't matter if he chooses honestly or privately flips a coin or makes them play a game of Connect4 for it, this movement will be stronger in November if he chooses.
The choice is probably tricky though. Both candidates are friends of his. His views align more closely with the Constitutionalists, but it could be misunderstood or be seen as a 'mixed' message if he endorses a minister. I don't think he is worried about rocking the GOP boat. He has repeatedly and convincingly admitted in interviews that he will not be endorsing McCain. Good, because in fact, to hell with the GOP. We are the true Republican party anyway.
