I don't know where you came up with that "three votes per precinct" statistic, but you're way, way off.
California has a total of 25,702 precincts. Gore beat Bush by 1,293,774 votes in 2000. That's just over 50 votes per precinct.
And yes, that is a very high hurdle indeed for Republicans to overcome.
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?
