Your inability to play in those events here have absolutely nothing to do with WGT, but solely with your state legislature. As far as your petition goes I think you have a tremendous uphill battle against your hands to make even a ripple in the pond. However, I do wish you the best of luck though.
Online poker has nothing to do with the US at all and in fact is an issue within the US government. Any site that you are playing real money poker games at, like FTP, are operating offshore and US laws cannot be enforced upon them on international lands. The practice is in fact illegal, and technically you are breaking the law by playing. Why do you think it is difficult to make deposits at these places? Some credit cards and banks turn down the transaction. The same holds true for online sportsbooks. The US might as well legalize it, regulate it, and tax it, because they'll never stop it. Although I also feel the same way regarding a certain herbal substance. ;)
