Care to guess who was the treasurer of Planned Parenthood when it launched its first national fundraising campaign in 1947? It was Prescott Bush, father and grandfather of the two Bush presidents.
Recall that contraceptives were controversial in those days -- and remember that a constitutional right to use them wasn't established until 1965, when the Supreme Court affirmed an implied right to privacy in Griswold vs. Connecticut.
Prescott Bush won a Senate seat two years later, and his son George and daughter-in-law Barbara continued to support Planned Parenthood even after George's election to Congress from Texas. In fact, he was such an advocate for family planning that some House colleagues gave him the nickname "Rubbers."
