We'll see what comes of this as Biden was quite obviously testing the waters. I think the big difference is the subject at hand rather than the usual mundane issues that executive orders normally deal with. Obama has stated many times his opinions of the Constitution as not being relevant. I'd rather not fix what isn't broken, in my opinion, because of the "need for action" and an emotional response rather than one based in logic. Let Congress "try" to do their job and leave the executive order process out of this. Even if he attempts to limit magazine size by executive order he's out of line. We'll see...
Executive orders are not usually about mundane things at all. Sometimes they are, but things like the warrantless wiretapping program, approval of torture, the Kosovo campaign, etc, etc, were all executive orders.
This is nothing new, and it is curious that the outrage over use of executive orders relating to constitutional rights was so silent until now.
