All the affiliates I’ve heard cry for a new payment processor.. not to have gambling legalized.
Many affiliates do want legal gambling in the US, it’s all over this and other forums, plus if it was not true, this thread would not have been so many pages 
A few thing I would like to add:
This is probably the only time I wish I was wrong. Let hope so.
Also – 888, Party Poker etc. – those are no big boys. If they were – they would not have left the US market, but fight the bill.
And again – when it comes to land-based casinos operating online casinos – there will be nothing to research. They would come strong as “regulated” casinos, they would offer tangible comps, they will raise awareness about online gambling only at “regualted online casinos”, etc. Those are very powerfull companies and they will get the full support of government and law.
And as far as affiliates come – they will have no power and will ahve to go by what the casinos say.
I mean – look at the current situation – affiliates are getting less and less powerful each day, half of the aff programs on CAP have broken their T&C, and whatever programs are left in the US market are lowering commissions, changing terms big time, etc.
And this is happening while we are still the only source of traffic the online casinos in US have. Can you imagine what will happen if they were able to advertsie on TV and all media? Look at VIP Profits for example – their commission structure starts at 20%. When was the last time any Rev started at 20%??? Can you imagine what a legalized onlne casino which is based on a corporation will give you?
And axl is right – America has such a trade deficit, that it is ridiculous to think WTO can do anything, especially about online gambling…
