Early polling also shows signs of increasing intensity among conservatives and Republicans in the wake of Roberts’ decision. In the first survey since the ruling, Gallup found that Americans are split down the middle — 46 percent to 46 percent — on the question of whether they agree or disagree with the Court. But when asked what should happen next, significant differences emerged. Sixty-five percent of Democrats said they want to see the law kept in place and the government’s role in health care expanded. But 85 percent of Republicans said they want to see Obamacare repealed either in whole or in part. It’s possible that in the wake of the Supreme Court’s ruling, a long-running trend in opinion — that Republicans dislike Obamacare more than Democrats like it — will become more, not less, pronounced. …

On that last note — it’s not clear how the Obamacare ruling will affect Mitt Romney’s presidential bid. But if conservative anger continues to grow, Romney will have a real opportunity to channel that intensity into support for his campaign — if he will make absolutely clear, in forceful language, that he believes the Supreme Court decision was wrong and that he will redouble his determination to repeal Obamacare.
