Neither the Republicans nor the Democrats have a consistent pro-live policy. As my wife says, the Democrats want to kill you before you’re born and the Republicans want to kill you after you’re born.
I would add to the non-negotiable items: denying health care to the ill, opposing a living wage to workers, and racism.
And as a personal aside, I would take down all Ten Commandments plaques at courthouses and replace them with the Sermon on the Mount.
