Why do it now, since it is very short time for September, and that time does not really matter anything on regulation level? Or are the scheduled votings coming very very soon?
This holds strong arguments against new regulations whether it was leaked or not. Difference being specific attention.
You can't forecast vote outcomes. Remember, politics is squishy. The totality of a policakers decision-making is more than just the facts, like it or not. How they are feeling toward you, the interests they perceive you advocating, how dedicated you appear to "the public interest" all factors into that Yea/Nay decision, and could be the difference between a relatively draconian statute NOW, or something so wishy-washy and limp-wristed you barely have to bother the accountant at all to adjust fiscal plans.
Perception management is a full time job, and at the core of marketing, lobbying, PR, and corporate strategy. If information does get out, it's because someone either blew the whistle, or because someone is fishing/doing clandestine signaling.
I'll be honest, it strikes me more as whistleblowing in this case; but there has been enough concerted effort at syndication I'm not necessarily closed to a strategic leak.
