Even though it will probably help the Dems to abandon "abortion rights," and possibly capture some of the support the moral high-road has given the Republican party, it is a wonderful thing!
I think they will begin drifting, ever so slowly away from defending Roe, unless they are in safe, commie urban areas like San Fran.
Of course, it could happen that the Pro-Choicers get disgusted with the Democrats and decide to go third party. I am sure Abortion will remain a plank in the Green Party Platform for the forseeable future, since it fits in with all their greenie-weenie population control nonsense.
If a serious third party movement captures even a portion of the Pro-Choice crowd, the Donks are toast, forever. Political parties come and political parties go. You don't see any Whigs around, anymore, after all. This may be the end of the Democrat Party.
