the PDC issue is quite interesting. What I see failed to be mentioned, is that no one is telling the tribes how they can spend their money; rather, they are, or should be, restricting what money the politicans can accept. A big difference. They likely can influence through their own ads and advertising, but any direct payment should be able to be stopped. There is no freedom of speech issues or federal issues that I see with this, as in no way is the tribe being regulated, only the non-tribal entity.
