Unless Sporties are willing to all pitch in more than they do now (We're talking about a group that bitches loudly about $0.15 Corkies being overpriced), lots and lots more, airing primetime TV ads, newspaper features, billboards, and greasing many an Olympia palm.
I frankly don't see it happening as I know too well most WA sporties would rather put their hard-earned $100 towards filling up their Truck & Boat's gas tanks and buying a halfrack of Busch Light.
Where as the Commies, they aren't nearly so pennywise and poundfoolish, they know (Its been an American Corporate Practice for 175 years at least) that by banding together into what used to be called a "Trust" but is now called a 'business association' with a smirk. This is where all the owners of the 'competing' businesses meet together, set market prices, wages & supply costs, agree on legislative goals, and set quotas, etc. They aren't so stingy and to let a few thousand bucks of chump change here and there come between them and $15 million annual Profit.
Would you spend $15,000 in Olympia to pick up $15,000,000? Yeah thats what I thought.
