Preliminary comments about pre-filed and early bills are fun to read. It is a very rare occasion when a bill goes from "pre-filed" status to the Governor's desk and becomes law without any changes in wording and/or intent. Making law is very much an exercise of "give and take". Bills get amended in committee. Bills get amended on the floor. Bills sometimes get rewritten entirely, with every word changed and even the subject matter of the bill different from the original. That is what was done with last year's pension bill and the reason that bill is now being challenged in court.
It is not unusual for a sponsor to give up parts of his bill in order to get the other, more important parts, passed. It is also not unusual to see that same legislator come back the following year and try to get those pieces that he traded away put back in. It is often easier to build support for a bill while part of it is actually law. Small bites are easier to swallow one at a time. Our present concealed carry law has been amended at least 20 times, some years with multiple changes. If the original sponsors of that bill had held out, all or nothing, for the wording we have now, we would have never gotten concealed carry. It was spoon fed to the opposition, year by year.
I would not be surprised to see some changes to BR 97 before the session actually starts, in Jan. I would say the same thing about all of the pre-filed bills. Who knows what any of them will look like when the session gets started. None of this is absolute.
