During the 2016 election, reproductive rights groups have consistently called on debate moderators to ask questions that would examine the candidates’ positions on abortion-related issues, but moderators have either ignored the call or centered their questions around  judicial appointees or the candidates’ religious views.

Although faith and judicial appointments are important topics, limiting debate discussions of abortion to only these contexts deprives the public of an opportunity to understand the candidates’ positions on an essential issue: access to reproductive health care.

On October 12, the Commission on Presidential Debates released the topics for the third and final presidential debate. Although the list includes the Supreme Court, it notably excludes any explicit mention of reproductive health or abortion -- making the likelihood of a question about the topic on its own merits unlikely.

What is likely, however, is that if the topic comes up, the moderator will either frame it around the candidate’s religion or ask whether they would screen their judicial picks for pro- or anti-choice positions.

In a recent analysis, Media Matters analyzed all abortion questions asked in presidential or vice presidential debates from 1960 to 2012 and found that 56 percent were framed around religion or used abortion as a litmus test for judicial appointments. In both instances, questions were often asked in a way that stigmatized abortion -- suggesting that the common and legal medical procedure was morally wrong or socially unacceptable.

The pattern has been borne out in each of the debates this year.

For example, the first presidential debate on September 26 did not include a single question about abortion or reproductive health care despite efforts by a coalition of reproductive rights advocacy groups. They encouraged NBC’s Lester Holt to ask the candidates how they would “address the crisis in abortion care in our country.”

In the second presidential debate, on October 9, the only mention of reproductive rights came during a question about the nomination of Supreme Court justices -- when Democratic presidential nominee Hillary Clinton mentioned that her ideal nominee would support upholding Roe v. Wade. If history is a guide, this line of questioning will be repeated for the last presidential debate, as one of the topics is the Supreme Court.

During the October 4 vice presidential debate, CBS’ Elaine Quijano asked Republican candidate Mike Pence and Democrat Tim Kaine an open-ended question about how they “struggled to balance [their] personal faith and a public policy decision.” As ThinkProgress’ Tara Culp-Resser explained, Pence “quickly pivoted to abortion” in his answer, while Kaine, “followed up by saying he trusts women to make this moral choice for themselves.” Although the candidates addressed abortion, as Culp-Resser pointed out, “ the exchange was ultimately situated in a religious and moral context that does a disservice to the bigger issue.”

In an October 5 article for The New York Times, Katha Pollitt explained why having candidates discuss their abortion positions only in relation to their faith was problematic. She wrote:

“I wish we didn’t so often discuss abortion rights in the context of religion. We’re not a Christian nation, much less a Catholic or evangelical one. Why should women’s rights have to pass through the eye of a theological needle? Given that the next president will nominate at least one and probably two or three more justices to the Supreme Court, it’s discouraging that we are still talking about abortion as a matter for biblical exegesis.”

Given the escalating assault on reproductive health care access, it's high time that debate moderators ask substantive questions about abortion that do not focus exclusively on religion or the court and that do not stigmatize the issue. There is a crisis currently underway, and it is likely the presidential nominees have differing views on how to address it -- distinctions the viewing public deserve to hear, and distinctions that can’t be determined by rote questions about religion and litmus tests.

The final presidential debate will be held on October 19, and if the moderator, Fox News’ Chris Wallace, doesn’t ask about abortion, the 2016 election will be the first since 1976 to include no direct debate questions about reproductive rights.
