Analysis: Majority in US back abortion rights, but support may be smaller than you think

Roe v. Wade, among other things, gave women the unimpeded constitutional right to an abortion in the first trimester. Perhaps not surprisingly, somewhere around 60% of Americans are in favor of keeping first-trimester abortions legal.

It depends on the question

From there, support for abortion rights declines.

When asked whether they want abortion to be always legal, mostly legal, mostly illegal or always illegal, a split public emerges. An AP-NORC poll from last year that 23% thought abortion should always be legal, 33% said it should mostly be legal, 30% said mostly illegal and 13% believed it should always be illegal. (The results line up with the long-term average percentages on this question.)

What these findings tell is that few Americans want abortion to always be legal and even fewer want it to be always illegal. Instead, the abortion debate comes down to coalitions.

In this case, the coalition who want abortion to be at least mostly legal (56%) outruns the coalition that wants it illegal at least most of the time (43%).

An even different question, but one that should be familiar to followers of the abortion debate, is whether people label themselves “pro-choice” (normally framed as pro-abortion rights) or “pro-life” (normally framed as anti-abortion).

Here, Gallup has consistently found a near even split. Last year, it was 49% pro-choice to 47% pro-life, a result well within the margin of error.

In terms of specific time frames, support for abortion rights drops after the first trimester. A recent Wall Street Journal poll found that slightly more Americans (48%) were in favor an abortion ban after 15 weeks than not (43%), if there were exceptions for the life of the mother. This is in line with previous AP-NORC polling showing that only 34% think abortion in the second trimester should be always or usually legal.

When you see these different results, you get to understand why surveys on Americans’ opinions of abortion often raise more questions than they answer.

Where the voters are

That said, the ballot box does offer some clues about the questions we should focus on to understand where American voters are.

Since 2018, there have been five ballot measures (Alabama, Colorado, Louisiana, Oregon and West Virginia) that sought to limit abortion rights. Not all of them had the same wording, though the results were basically what you’d expect, given the politics of each state.

Alabama, Louisiana and West Virginia voted in favor of limiting rights, while Colorado and Oregon went in the other direction.

More interestingly, the results of those ballot measures matched up very well with the percentage of people in those states who think abortion should be always or mostly legal.

Using data compiled by the New York Times’ Nate Cohn on this question, I calculated that the absolute average difference was just 4 points between the margin on the ballot measure result and the margin in polling between “always or usually legal” and “always or usually illegal.” The median difference was a mere 2 points.

The only real outlier was West Virginia, where a surprisingly low 52% of voters cast a ballot against a constitutional right to an abortion. Polling in this very red state has generally indicated more opposition to abortion rights.

Remember, more Americans believe abortion should usually or always be legal than not, so on this key question, it’s fair to say the pro-abortion rights coalition is bigger than the anti-abortion one.

Of course, this isn’t the case in every state. Although the polling is close, there are about 15 states where more residents than not think abortion should be always or mostly illegal.

And if Roe v. Wade does get overturned, it’ll ultimately be this state-level polling that matters most.
