Back in the Nixon administration, George Bush (the elder) congratulated family planning advocates on all their successes:

As United States Ambassador to the United Nations under the Nixon Administration, President George H.W. Bush (the first President Bush) wrote a letter to Alan Guttmacher (founder of the Guttmacher Institute) congratulating him on creation of a "family planning" stamp commemorating (gasp!!) Margaret Sanger.

This was in the good ol' days: Republicans were for it before they were against it. The Bush family sat on the board of Planned Parenthood and in numerous and sundry other ways supported global efforts to promote access to family planning services.

While women's rights have always been political, this was before it became fashionable and politically expedient to quite obviously sacrifice both evidence and women's bodies openly on the altar of electoral gains.
