“As recently as April, Republicans and Democrats had virtually identical positive opinions on the Supreme Court. But not any more,” adds Holland. “That’s the biggest change that the court decision has created.”

The court’s approval rating among Democrats jumped by 23 points; to 73%. Among Republicans, it fell by 21 points, to 31%. Approval of the Supreme Court among independents edged up five points, to 53%.

Not surprisingly, opinions of Chief Justice John Roberts are also divided along partisan lines, with a majority of Democrats holding a favorable view of him compared to only three in ten Republicans. But more than a third of all Americans are unsure how they view Roberts, probably a result of the low profile that he and his colleagues have kept for many years. Roberts sided with the liberals on the high court to uphold the law.
