Withhold funds from US PIRG

I was canvassed tonight by US PIRG.  Since the PIRG entities are the children of Ralph Nader, I told the canvasser he would not get a dime until Nader dropped out of the race.  Everything Nader and PIRG have been working for will go up in smoke if Bush is elected.  I also told him I would send the canvasser a check for $100 the day Nader drops out.  

Please either join me, or give me a better idea of putting some pressure on Benedict Nader.
