New national Marquette Law School Poll finds public approval of the Supreme Court to be high, partisanship to shape views of justices and decisions

MILWAUKEE — A Marquette University Law School poll of adults nationwide finds 60% saying they approve of the way the U.S. Supreme Court is handling its job, while 39% disapprove and 1% do not offer an opinion. By comparison, in the same national poll, 58% approve of the way President Joe Biden is handling his job as president, while 42% disapprove. The U.S. Congress fares worst of the three branches, as 33% among the public approve and 66% disapprove of how Congress is performing its duties.

Over the past year, approval of the Court has declined six points, from 66% in September 2020. Disapproval rose a corresponding amount, from 33% to 39%. Asked which branch of the federal government they trust most, 58% of respondents say they trust the Court most of the three branches, with 28% saying they trust the presidency most and 13% saying they trust Congress the most. In the 2020 national Marquette Law School Poll, 59% said they trusted the Court most, with the presidency at 24% and Congress at 16%.

The Marquette Law School Poll previously conducted national surveys of public opinion and attitudes about the U.S. Supreme Court in 2019 and 2020. This new poll reflects an expansion of this initiative, which will see a similar national poll conducted every other month for the next year. This survey was conducted July 16-26, 2021, among 1,010 adults nationwide, with a margin of error of +/-3.9 percentage points. Interviews were conducted using the SSRS Opinion Panel, a national probability sample with interviews conducted online.

Approval of the Court varies little by party in this survey, whereas partisanship played a larger role a year ago. Tables 1 and 2 show approval of the way the Court is handling its job, by party identification for 2021 and 2020. Democrats and Republicans have similar approval ratings of the Court this year, but in 2020 Republicans were much more approving of the Court. This shift is striking because the 2020 survey was completed before Justice Ruth Bader Ginsburg died, so the decline in Republican approval comes despite the addition of Justice Amy Coney Barrett, who was appointed by Republican President Donald Trump.

All numbers in tables are percentages unless context indicates otherwise.

Despite the intense arguments over the Court in partisan circles, perceptions of the Court’s makeup have changed only modestly since Barrett’s nomination gave Republican presidents six appointments to the Court versus three appointments by Democratic presidents. Fewer than a third of respondents say Republican presidents have “definitely” appointed a majority of the Court, while just under half say they “probably” have appointed a majority. Almost a quarter say Democratic presidents have probably or definitely appointed a majority of the Court. Perception has shifted slightly over the past three years, with more awareness in 2021 of a Republican-appointed majority, as shown in Table 3.

Knowledge of the partisan majority—a shorthand term used in this release simply to refer to the party of the appointing president—varies substantially by party. Despite three appointments to the Court by Donald Trump and frequent public references to Republican emphasis on judicial nominations, only 16% of Republicans say Republican presidents have “definitely” appointed a majority of the justices. By comparison, 44% of Democrats know this fact. Table 4 shows awareness of the partisan majority by party identification.

Republicans who think Democratic presidents have appointed a majority of the Court (30% of all Republicans) are much less approving of the Court than Republicans who know there is a Republican-appointed majority. For independents and Democrats, those who say Republican presidents have definitely appointed a majority of the Court are less approving than those who say there is “probably” a Republican-appointed majority or who think there might be a majority appointed by Democratic presidents. Table 5 shows this relationship.

Institutional change

Expansion of the Court has become a frequent topic of debate following recent confirmation battles in Congress. In the new national Marquette Law School Poll, 48% favor increasing the number of justices on the Court, while 51% oppose such a structural change.

On the issue of expanding the number of justices, the poll shows substantial and symmetric partisan differences, as shown in Table 6, with Republicans heavily opposed to an expansion and Democrats heavily in favor. Independents are, on balance, somewhat opposed.

A majority of the public thinks that justices should not consider partisan control of the presidency and Senate when deciding the timing of their retirements. However, when given information about some Democrats urging Justice Stephen Breyer to retire now with a Democratic president and Senate, more people support retiring with politics in mind, though it remains a minority.

When asked “Do you think Justices should consider the party in control of the White House and senate as they decide when to retire?” 28% say justices should consider party control, while 72% say they should not consider this. This item was asked of a random half-sample of the survey.

The other random half of respondents was provided more information and context in the form of an alternative question worded this way: “Justice Stephen Breyer is 82 years old and the oldest member of the Court. He was nominated to the court in 1994 by President Clinton. Some Democrats are urging Breyer to retire now while there are a Democratic president and senate. Do you think Justices should consider the party in control of the White House and senate as they decide when to retire?” With this wording, 39% say justices should consider party control while 60% say they should not.

The partisan information boosts support for political timing of retirements across partisan identification, especially among Democrats, as shown in Tables 7 and 8.

Cases and decisions

While some Supreme Court decisions break through to public awareness among almost all citizens, most cases struggle to reach even half of the public. Six cases handed down in June or early July illustrate this range of visibility. They also show that, among those who have heard of them, a plurality supports all but one of the decisions, with substantial plurality support for three of the six decisions. Table 9 shows these decisions in order from least visible to most visible. The exact question wordings describing these cases were paraphrases of the way the cases were described in leading newspaper coverage. The full wording of the questions is given at the end of this release and is also available in the complete survey instrument posted online.

Perceived ideology of the Supreme Court

The Supreme Court is perceived as a center-right institution. Thirteen percent say it is very conservative, 37% say it is somewhat conservative, and 42% call it moderate. A small set of respondents (6%) see the Court as somewhat liberal and 1% think it is very liberal.

Perceptions have shifted a bit to the right since September 2020, when 5% said the Court was very conservative, 30% called it conservative, and 54% labeled it moderate, while 9% said it was liberal and 2% called it very liberal. (The category labels changed from 2020 to 2021, replacing “conservative” with “somewhat conservative” and “liberal” with “somewhat liberal,” so it is possible that this change in wording affected the results independently of changes in public perceptions.)

Compared across political institutions and actors, the Court is on average seen as closer to the center than is the Republican party and closer to the right than is Joe Biden or the Democratic party. Table 10 shows the average position on a 1-5 scale, where 1 is very conservative and 5 is very liberal.

While the public sees the court as leaning to the right ideologically, a substantial majority (71%) say the justices’ decisions are most often motivated by the law, while 29% say decisions are mainly based on politics. In the 2020 poll, 62% said the law was the main motivation of justices, and 37% said it was mainly politics.

A majority of each partisan group says the justices are mainly motivated by the law, though the majorities are somewhat smaller among Democrats than among Republicans or independents. Table 11 shows responses by party.

The public’s views of the justices

The justices are not well known among the public. Nearly a quarter of respondents (24%) say they do not know enough about any of the nine justices to give a favorable or unfavorable opinion about them. Another quarter, 27%, are able to rate one, two or three justices. Twenty-three percent are able to rate four to six justices, and a final 26% can rate seven to nine justices.

Individual justices vary considerably in their visibility to the public. Table 12 shows the justices in order from least well known to most well known.

The order of justices by visibility is little changed from a year ago, with Barrett as third-most visible; on the Court, she replaced Ginsburg, who was the most well-known prior to her death in 2020. Breyer, Alito, Kagan and Gorsuch were the least well-known both years. Chief Justice John Roberts has been in the middle of visibility, with just over 40% able to rate him in both 2020 and 2021. The corresponding ratings of justices in September 2020 are shown in Table 13.

How knowledge and partisanship structure views of the Court

While the Supreme Court has been embroiled in political fights over appointments and high-stakes decisions on cases, and many party and interest group activists see the Court as crucial to their political and policy goals, the Court is, for the mass public, a somewhat distant object. Most citizens can offer generalized views of approval or ideology or trust, but specific and detailed knowledge is often lacking. While virtually all respondents are willing to give an approval rating or place the Court on a liberal-conservative ideology scale, only about half, 51%, say the choice of the next justice is “very important” to them personally, only 58% can say whether they have a favorable or unfavorable opinion of the best-known justice, while one in four (24%) state they don’t know enough to rate any of the nine justices, and 18% do not know enough to offer an opinion of any of six cases decided in the previous two months.

While it is common for voters to lack detailed knowledge of policy, procedure. or elected officials, the Court falls at the low end of visibility. It is not uncommon for a quarter to a third of voters to lack a favorable or unfavorable opinion of their U.S. senators, yet 42% were unable to give an opinion about the best-known justice, and 76% lacked an opinion of the least-known justice. Many voters are unable to give the name of their member of the House of Representatives. In light of this, it is not that the Court’s limited visibility is unique but rather that it represents the low end of a continuum from the highly visible president, through governors, senators, and members of Congress, to the Court.

An important implication of this is that the structure of opinion about the Court may differ substantially between those who have high interest in it and those who only casually attend to the Court, with rare exceptions such as confirmation battles or landmark decisions.

While opinion is often only loosely informed, citizens still form generalized opinions about the Court in much the same way they form opinion about other less-than-universally known political actors and policy. In particular, they rely on partisanship and party cues.

A first consequence of the information gradient is that those citizens most interested and most informed have the most divided views of the Court, while the less attentive tend to view the Court in a more positive light.

Those who say the next appointment to the Court is very important to them personally are about evenly divided in approval of the Court, while those less concerned are notably more approving, as shown in Table 14.

Somewhat important68320

Not at all important62380

A similar pattern is evident for knowledge of decisions and of the justices. Those in the best-informed categories are considerably more divided in their views of the Court than are those with more limited knowledge. Table 15 shows the differences by knowledge of recent decisions, and Table 16 shows differences by ability to give an opinion of the justices.

The partisan structure of opinion about the Court

Despite the limitations of knowledge about the Court the public manages, in a rough way, to match its partisan positions to its views of the justices and the Court’s decisions.

With the sole exception of Chief Justice Roberts, net favorability aligns with the partisanship of the respondent and the party of the president who appointed the Justice. This pattern holds for the less well-known justices (Breyer, Alito, Kagan, and Gorsuch) and for the more widely known justices (Sotomayor, Barrett, Thomas, and Kavanaugh). Roberts alone is more positively evaluated by Democrats than by Republicans, despite his appointment by Republican President George W. Bush. Views of the justices by party are shown in Table 17.

Political partisanship also correlates with reactions to cases with a notable partisan tilt in the lineup of the justices (in the respective majority and dissent) or with a partisan bent in their dominant public characterizations, including the Arizona voting rights, California donor disclosure, Philadelphia Catholic Social Services, and Affordable Care Act cases. Views of other decisions, with a less clear partisan connection, including the school speech and NCAA antitrust decisions, vary less by partisanship, although Democrats favor the decisions somewhat more than do Republicans. These relationships are shown in Table 18.
