If you do this though, they won't see how much of their lost support was from the libertarian wing of the party...so they won't have as much incentive to change in our direction.
If McCain wins all our work will be gone and when we go back to the GOP they will continue to ignore us. If he gets hammered and loses badly our voice will be heard.
Did they give a shit when Ross Perot took almost 20% of the vote - hell no. The leadership will look real stupid with a big loss and will shake it up. If McCain wins we are screwed!
