But by earlier this month, the ratings had dipped back down, and surveying done after the Supreme Court's decision Thursday did not seem to significantly move American opinion.

Dismayed conservative commentators have suggested that Chief Justice John Roberts might have split with liberals on the controversial 5-4 decision in hopes of boosting public confidence in the court after divisive rulings in the Citizens United and Bush v. Gore cases.

"The chief, who made the protection of the court’s institutional image and entirely persuasive power his foremost goal, has gutted the limitation on enumerated powers to achieve that goal," wrote Thomas Crown on the popular conservative blog Red State.

But it might take more time for the true ramifications for the court to be observed. The Rasmussen survey included polling conducted the day before the ruling, and did not disclose how many of the 1,000 respondents were contacted after the court's ruling.
