It seems to me that pro-life is already out of the party and that the GOP is already dead.
From what I can see at this point, the GOP is going to try to build a coalition that does not include pro-life, which to me does not seem like a smart move, but pro-life cannot be counted on anyway as shown in the last primary and election.
Divided we fell.
If pro-life is already out of the party, then you can drop your crusade to drive it out.
