Are the current sites against poker 'legalization' in the US?

[questions]

I was thinking about this - it does make a certain sense to reason that those who currently profit from providing a form of entertainment which is frowned upon by society would have an interest in maintaining the status quo, for a number of reasons. However, don't forget that those who run the sites are people, too, and would also benefit from a legalized environment, to the extent that they can market their own professional expertise to legit sites in a post-legalized world.
