One may call it a "wedge" issue,
But would it be if Kasich, Cruz, Rubio or even Rand Paul was the nominee? They are had strident pro-life views. And in the case of Kasich, probably the most accomplishments.
Likwise, though some might question Romney's pro-life creds, when he ran his campaigns, I was not all of a sudden doubting him and taking Paul Ryan up as Veep added to it.
No, states, including back East in New Jersey and who knows where else besides the often mentioned Texas, Wisconsin, Ohio, all defunded Planned Parenthood. This is not a dead issue, it is a live issue and it could very well be done on a National basis.
