Honest question that I honestly don't know the answer to.
I can see how a man would just slow her down; classically trained pianist, Soviet Union specialist, provost of Stanford, only one of two women to be a member of Augusta Country Club, National Security Advisor, Secretary of State, and now head of The Hoover Institute.
I can also see how she has kept her lesbianism to herself. Her mom died young, her dad was a Presbyterian minister, she is a Republican, let alone an African American woman who accomplished the aforementioned.
My answer is she most likely is and never bothered to find love, which is extremely sad. But I get it.
