This is actually untrue in Massachusetts she can veto anything with a cost attached to it as a line item according to GOALNo, she cannot cherry pick what she wants to pass. She either passes it as it is or vetoes it and sends it back with notes on what she will pass.
I see her letting it sit so she can’t be blamed when the law is so brazenly anti 2a it gets the entirety of our gun control tossed via lawsuits
