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

[Dire]

So I was reading this thread about how Barry G predicts online poker [in the states] will likely be 'legalized' within 6 months, and how the PPA has been putting forth a great effort to further such legalization, so fourth and so on.

What's always seemed odd to me about this whole regulation issue is that there's never really been any major/visible lobbying from the current sites to regulate and legalize poker in the states, in spite of the fact that the US makes up a huge chunk of all online poker players. They did effectively nothing prior to the UIGEA as well.

And then I realized something. If poker is legalized, it could spell the end for these sites. Everybody's talking about how incredible it would be to have access to Party again, but poker.bellagio.com / MGMpoker.com / etc will make Party look like a rock garden. The names and security alone will bring countless fresh schools to the new name sites, which will also take the high volume regulars away from Stars/Tilt/Party/etc and onto the 'new' sites.

Are the current sites against regulation? Do you think they were against any sort of regulation prior to the UIGEA and may have even been indirectly in favor of the UIGEA? I mean it has been quite predictably ineffective at preventing people who want to play online from doing so, but at the same time it's been extremely effective at ensuring no new major competition for US players springs up. This seems so tin foil hattish, but it sure makes alot of sense right now.
