I suspect because Marco Rubio is sponsoring it that 1) a draft may already have some bipartisan support, and 2) it probably is rolling immediately off the state python phase-out/ban just implemented by Florida about 10-14 days ago.
In this case, because it is Congress/the Senate, this is much more likely (than was the emergency/admin rule of 2016 that took place in an agency vacuum) to be affected by a number of good, reasoned (=not rants) letters WITH SUGGESTED ALTERNATIVES (like BSal testing) from constituents to the committee members. In addition to a letter perhaps signed by the admins of Caudata (mentioning total US membership if that kind of data can be harvested) a letter writing and phone call campaign from individuals to their respective Senators at the current stage (bill in committee) can make some difference. Congressional staff do count response, but again no matter how frustrated, folks should try to avoid rants, saying "just don't do this," and then suggest reasonable alternatives. People need to act fast though because once it gets out of committee it will be harder to get changes.
Though USARK I'm sure will be heard, they are going to be representing the python breeders more than anything. People need to engage politically if they want any hope of getting reasonable change made before it gets out of committee.
