Actually, Hillary would be leery of being too anti-gun. She would look at elections past and her calculating mind would realize that it would cost future votes.
JulieAnnie would not care. He would consider his election proof that pro-gun voters are irrelevant.
I predict if Hillary is the nominee at some point we will see a photo-op of her on a hunting trip with Bill somewhere in Arkansas. Bill will be wearing body armor to protect himself from a friendly fire "accident".
