She was a party girl for decades and Willie Brown concubine. Then she decided at 50 it was better politically to marry. No children. Number of abortions is unknown.
She did well for herself. She wasn't that bright. But she was "street smart". She knew how to work the system to where she is today.
I doubt that she wanted to have children in the first place. She gets to have a "family" through Doug without having to do any work.
