"The dims may go down with the ship rather than throw this issue overboard."
There is always a chance that this will be a grand slam HR for the GOP with the Dim potty splintering into two or more parties, one the traditional Dims (whatever the Hell that means) and then, of course, the anti-war but kill the babies party.
It's possible. They split over national defense in the 1970's. And since Roe a lot of Catholics and evangelicals who traditionally voted Roosevelt Democrat drifted over to the pubbies. I just don't know if there are enough pro-life Democrats left to challenge the establishment or establish a new party.
A pro-life Democrat is running for Governor here and the Dims have made him pinky-swear he won't make any pro-life changes to state law or regulation, and they still may deny him the nomination.
