If you think keeping abortion within the sole purview of the Feds(Dems) is going to result in an across the board ban; then you're delusional.
Withing the present framework you are never going to get a federal ban. There's an alternate definition for a word that goes something like this: 'doing the same thing and expecting different results.' The word: Insanity.
I suppose it is desirable to you to have a federal ban, but the question is; would you prefer to go for a federal ban, that you're never likely to get, or go with a 25~50% ban on the state level and work from there?
We've been trying for about 30 years now to ban it, and we're not making much headway.
Time to change tactics.
Actually, that's the one thing our "leaders" HAVE NOT been trying to do.
