The below came over the transom, but I see that the facts were extracted from this article in the WSJ:
She graduated from Southern Cal and was a special-needs teacher.
After her Dad died, she became involved with his beer-distributing firm and is now the chairwoman. Sales have doubled since she has taken over from her father.
They have a marriage prenuptial agreement, her assets remain separate.
She is involved around the world clearing land mines - travels to these countries on a detonation team and serves on their board.
They have a 19-year-old serving in Iraq, another son in the Naval Academy, a daughter recently graduated from Columbia Univ., an adopted daughter in high school, and a son who is the finance guy at the beer firm.
Raised kids in Phoenix, AZ rather than Washington DC. (Better atmosphere) He commuted.
In 1991, Mrs. McCain came across a girl in an orphanage in Bangladesh. Mother Teresa implored Mrs. McCain to take the baby with severe cleft palate. She did so without first telling her husband. The couple adopted the girl who has had a dozen operations to repair her cleft palate and other medical problems.
They have a Family Foundation for children's causes.
She is active with "Halo Trust" - to clear land mines, provide water and food in war ravaged and developing countries.
She will join an overseas mission of "Operation Smile", a charity for corrective surgery on children's faces.
She has had two back surgeries and became addicted to pain killers. She talks openly about it, which she says is part of the recovery process.
I am surprised the media is so quiet about her attributes.
