A survey from Pew Research shows a growing number of Americans have an unfavorable view of the Supreme Court in the wake of decision on Obamacare and same-sex marriage.

Following major, end-of-term rulings on the Affordable Care Act and same-sex marriage, unfavorable opinions of the Supreme Court have reached a 30-year high. And opinions about the court and its ideology have never been more politically divided.

Currently, 48% of Americans have a favorable impression of the Supreme Court, while 43% view the court unfavorably. Unfavorable opinions of the court, while up only modestly since March (39%), are the highest recorded since 1985.

The poll of 2,002 American adults was conducted between July 14 and 20th. The biggest increase in those taking a dim view of the high court was among Republicans.

Just 33% of Republicans have a favorable opinion of the court, while 61% have an unfavorable view. Since March, the share of Republicans viewing the court favorably has fallen 17 percentage points (from 50% to 33%), while the share with an unfavorable impression has jumped 21 percentage points (from 40% to 61%). Republicans’ views of the Supreme Court are now more negative than at any point in the past three decades.

In contrast, Democrats’ views of the Supreme Court have become more positive since March, though the change has not been as dramatic. Currently, 62% of Democrats have a favorable impression of the court, up from 54% four months ago.

While Americans overall increasingly see the court as leaning liberal, 68% of conservative Republicans view it that way.
