Will they be overturned in our lifetimes though? I'm sure plenty of people thought Roberti-Roos would be overturned when it was signed into law in 1989.Not sure which bill you are referring too with "this". If any of the bills are unconstitutional, they will be challenged and overturned. This has happened before with so many different types of legislation both related to the 2nd and not. Legislators from all parties make mistakes about constitutionality and that is one of the reasons we have courts.
36 years later here we are, waiting and praying for the SC to hear Miller v Bonta, since the 9th will obviously rule against us, whenever the hell they deign to rule on it.
