In regard to PPA:
Casinos have a connotation of “pure chance” gambling, and PPA is trying his darndest to distance Poker (a skill game, with element of luck) from the Casino games. I believe he feels that joining forces with a Casino organization will dampen any attempt he is making to separate the 2.
Again, this is all after the fact, and is a moot point, as the law will be signed this week.
