why was this law passed?

[ski]

I understand that there are probably a number of reasons.

I always thought the US just wanted a cut of the profits for online gambling in addition to pleasing the Christian and other lobbies that want to ban online gambling for moral reasons.

My question is what did Frist and the others responsible for online gambling language being attached to the bill gain? Has the language of the bill opened up doors for the US to somehow profit on this by allowing it to keep happening? It is difficult for me to beleive that this was attached for moral reasons + reaching "moral" voters alone.
