BUT, my central point remains. Let's grant your proposition. It will be hard. What does one do? Lie down? Give up? No thanks.
The logical conclusion is to take action, today. The higher the hill, the sooner we have to start climbing. Are you pulling or riding?
We each do those things which personally interest us and which we perceive to be valuable. You obviously want to put your time and effort into doing whatever you can to promote Bill Simon's candidacy. That's fine. More power to you.
I personally think that Bill Simon is the one who needs to get his campaign on track, if he's going to have any real prospect of winning. Without that, individual volunteers are not going to make a significant difference or sway the outcome. But that's just my opinion, and I could be wrong, so don't let me discourage you from volunteering.
As for my own volunteer efforts, I'm involved with several other initiative measures and campaigns (e.g., Tom McClintocks race for State Controller) which will keep me quite busy.
