This is a HANGING CURVE BALL for Trump - make it a BIG-TIME issue. Get the country talking about it. Make the Democrats GO ON RECORD nationally as supporting this horrific act.
I would say that this is a hanging curve ball for Republicans in general...but I already know that the vast majority of non-Trump (elected) Republicans would prefer that little girls be mutilated than have to address the issue. I’m not that dumb as to expect anything out of them.
In my book if you hold a little girl down and cut her anywhere, you have commuted a crime. No need for a special law.
