If their is a REAL Apocalypse the world will be thrust into anarcho capitalistic hunter-gatherer state and it will no longer be us vs them because all of their socialistic hopes and dreams will evaporate with no hope of implementation outside of small family-like communities.
Their would no longer be any central government to take from the rich and give to the poor. No more welfare, no more protectionism of pet classes, just every man for himself.
If they realize this, prepare, and fight for their own survival, they stand just as good of a chance as anyone else.
Everyone's chance would depend on their skill and provisioning. If they are very intelligent and have the skills needed to survive in anarchy, they will survive fine if they can conform to the new system of no system.
What are the chances of a liberal having the qualities needed to survive as opposed to a conservative?
I'd say less but not zero.
