Days after the Supreme Court delivered a victory for his health care law for the second time, President Obama flew into mostly Republican territory on Wednesday and began an aggressive push to get states that have resisted parts of the law to expand care to more of their poor residents.

“With the Supreme Court case now behind us, I’m hoping what we can do is focus on how to make it even better,” Mr. Obama said to an audience here that included health care administrators and people who got health insurance under the Affordable Care Act.

A new poll finds that most Americans approve of the recent Supreme Court decision preserving the health care law’s subsidized insurance premiums for people in all 50 states.

Overall, 62 percent approved, while 32 percent disapproved, said the survey released Wednesday by the nonpartisan Kaiser Family Foundation.

In his 1996 State of the Union address, President Bill Clinton proclaimed, “The era of big government is over.” That prediction turned out to provide more of a short-term rhetorical evasion than signal a lasting change in the direction of national policy. But after last week’s Supreme Court decision in King v. Burwell, it would be more accurate to say: “The era of big lawsuits against Obamacare is over” Nevertheless, several other types of challenges to the future path and pace of implementation of the Affordable Care Act (ACA) remain ahead. As one door closes, others open.

In the wake of the Supreme Court’s disappointing King v. Burwell decision, many are asking what comes next for those of us who have opposed Obamacare as a disastrous federalization of American health care. I predict that the Republican party will quickly divide into three camps on health-care politics.

After last week’s terribly disappointing Supreme Court decision in King v. Burwell, Obamacare opponents have fewer options. They should reexamine their well-worn playbooks of the past. More of the same will produce less and less.

By our count at the Galen Institute, more than 54 significant changes have been made to the Patient Protection and Affordable Care Act since it was enacted in 2010 – at least 34 that the Obama administration has made unilaterally, 17 that Congress has passed and the president has signed, and three by the Supreme Court.

Our latest count has added two more changes made by the Obama administration contrary to statutory language, and one rewrite of the law’s text from the latest U.S. Supreme Court decision.

House Republicans’ lawsuit against the Obama administration might have gotten an unexpected boost this week from the Supreme Court.

In a new legal filing Tuesday, attorneys for the House GOP said there’s a fresh precedent supporting their suit challenging the administration’s implementation of Obamacare—the Supreme Court’s ruling Monday on congressional redistricting.

Healthcare lobbyists across Washington are hoping to win long-sought changes to ObamaCare now that the Supreme Court has affirmed the law is here to stay.

Last week’s ruling in King v. Burwell has unfrozen the field for dozens of healthcare groups that have been stymied in their efforts to tweak the law while it was still fighting for survival in the courts.

These may seem like the darkest of days for proponents of free-market health reform.

The Supreme Court ruled in King v. Burwell that ObamaCare’s subsidies can flow to states that don’t set up their own exchanges, and a poll out last week found supporters of the law narrowly outnumbering opponents for the first time in years.

But a closer look at those poll results offers not only hope for a revival of free-market aims but a path forward.

The Supreme Court issued an order on Monday that allows certain nonprofit religious groups to avoid compliance with federal rules concerning insurance coverage of contraceptives for women.

The order bars the Obama administration from enforcing the rules against the religious groups and church officials until the court decides whether to hear an appeal they filed this year.
