All I will say is this: When I met my (now) wife, she was a total sweetheart, kind and thoughtful. She still is. She was very liberal when I met her, and even bragged that she would, “Turn me into a liberal soon.” (In a joking way). We have now been together for over twenty years and she is still a sweetheart, and a great mom.
And she is as conservative as I am, now, and has been for most of those years.
The moral of the story is some of them - some of them - can be brought to the Light Side.
