Damn those pesky little facts. Besides, No fault divorce only applies, if you don't contest it. SO if you want fault, then pay your lawyer and get fault.
And who passed the No Fault Divorce Law of California, before it got to Reagan’s desk?
Democrats.
As Gov he had the legal and Republican moral authority to reject it.
Again, setting the stage for his later policies of larger Fed and illegal immigration, he ran with the Dems and took their lead.
He was a huge RINO by today’s standards.
