I think its time to get realistic.
Ron Paul should ride it out so that he can speak at the convention, but i believe the majority of his time should now be spent publishing books, essays, and promoting other "liberty candidates." He should form more coalitions for certain causes (ending IRS, ending Iraq war, protecting civil liberties, free market) within congress as well.
All of these things will help us spread his message, since that is what it has always been about anyway. I hear he has a "manifesto" coming out soon.
As for us, we should vote for other "liberty" candidates, no matter what party they are in, and should start to look at maybe Ron Paul's (Rand) son as a future uniter.
