I am aware of at least three Libertarian Party presidential candidates who have expressed an interest in coming to San Francisco and speaking to local LP activists (something that Mr. Paul hasn't really done).
Two of the three informed me that they didn't detect any interest from Libertarian Party officers and luminaries, and were reticent to engage when it appeared that most of the LPSF leadership were campaigning for a Republican.
That's apparently the opinion of a goodly number of LNC members as well.
Make of that what you will. It doesn't bode well for LPSF's profile in the national party.
Cheers,
Brian
