The bill to amend title 18, United States Code, to include constrictor snakes of the species Python genera as an injurious animal will b e voted on. First by the Senate. Then by the House. Next it will be considered by the President. If it has passed, he will sign it into law. Just like the old cartoon of the Bill sitting on the Capitol steps.
I think what you are implying is that the Bill will go before a popular vote. This will not happen. Get out a basic U.S. Government textbook if you don't believe me. I hate to argue about this, but you are the one without any "actual facts".
Whether or not this ban is needed is debatable. In some states, notably Florida, feral constrictors are becoming extremely harmful to the ecosystem. The local wildlife up in Maine doesn't have much to worry about. It does seem unreasonable to ban them nationwide.
Another question is whether listing them as an "injurious animal" amounts to an all-out ban.
Does anyone know when the bill is due to be voted on by the Senate?
