I think in '08 Dr. Paul was certain that he wouldn't win the Presidency. He ran an educational campaign. Now he knows that if he runs, it will be to win. And there is a good chance he could get all the way to the general election, which would result in him winning (easily).
Remember what happened to the last real candidate we had in this country?
RFK had literally just won the primary when he was murdered.
Asking Ron Paul to do this is asking him to make the last act of his life a sacrifice for the rest of us. Think of all the things he'll miss out on. His wife, sons and daughters, his grandchildren. (even great-grandchildren?).
And what's the catch?
If he becomes president and lives the rest of his life unmolested, he will basically miss out on all of that anyway. Except now his family becomes a target of violence, too.
What I'm trying to say is,... no one can "ask" Ron Paul to do this. Not even Carol. I don't even know how a man can weigh the pros and cons of this. If it was me, i'd shit my pants and run and hide.
And for the rest of us, this is the beginning of the end of our Dr. Paul experience. We don't have much time left with him. I know a lot of us see him as something of a father figure. It is time for us to begin the transition from zealous followers to cunning r3VOLutionaries. Some of us have made that transition already. To be clear, a zealous follower works their ass off getting out the vote and educating his fellow man. A cunning r3VOLutionary requires no vote or violence, only volition. Their methods and tactics rarely draw any mass attention and yet their fruits greatly effect us all. They are the embodiment of the cause of Freedom.
Let us hope that we never have to make the transition from cunning r3VOLutionary to freedom fighter.
