Clearly you are implying exactly Condoleezza Rice, but if you look at the other companies she is a board member/advisor for you find a diverse groups of companies. It makes sense for someone who wants to stay current with the latest in business to seek a diverse portfolio of companies to be a part of.
One board member being formerly involved in politics doesn't strike me as valid the way you are comparing it to Theranos.
