This all depends on how you measure it. Take Roe v Wade for example. Abortion pre-Roe v Wade was really not that big of a political issue. Just yesterday I was listening to the radio on a long drive and a company called "Patriot Network" was advertising a cellphone network for "Patriots". The reason? Verizon and other big phone companies donate to Planned Parenthood.
"In 1971, delegates to the Southern Baptist Convention in St. Louis, Missouri, passed a resolution encouraging “Southern Baptists to work for legislation that will allow the possibility of abortion under such conditions as rape, incest, clear evidence of severe fetal deformity, and carefully ascertained evidence of the likelihood of damage to the emotional, mental, and physical health of the mother.” The convention, hardly a redoubt of liberal values, reaffirmed that position in 1974, one year after Roe, and again in 1976."

"Not that big of a political issue" is a pretty interesting take on a massive turning point in both women's rights and the drift of conservative America increasing to the right.
