You didn't answer the question. Also, Dems are the ones benefitting from this--not Republicans. Republicans would have fared far better if this hadn't come out. They have already been preparing for it with state laws set to become active the second Roe is overturned. Nobody needed to tell them this was coming.
The real benefit is to those who are horrified by it and will now have time to get ready for what they naively assumed would never happen.
It was a warning--not a moment of Republican braggadocio that motivated this leak, IMO.
And we still have no idea who leaked it.
