Another U.S. Supreme Court victory doesn’t mark the end of the road for the Obamacare story. Robert King reports for the Washington Examiner.

While the King v. Burwell decision keeps a major part of Obamacare in place, it also doesn’t mean the law is without any challenges.

Besides political efforts to repeal the law, which are sure to continue, efforts now turn to who enrolls in the exchanges, according to the research firm Avalere.

“Exchanges need to focus on increasing enrollment and attracting younger, healthier individuals in order to ensure a variety of affordable health plan options participate in the market,” according to Caroline Pearson, senior vice president at Avalere.

Nearly 12 million people enrolled in the marketplaces in 2015, and more than 4.1 million consumers under 35 signed up for coverage.

Getting younger people to enroll isn’t the only issue.

About 85 percent of Obamacare enrollees receive some form of subsidy. While those subsidies will now be protected, it means a majority of enrollees in Obamacare are lower income.

That could be a problem as the law needs to expand its enrollment to remain viable. But higher-income residents have not pursued getting coverage through the exchanges.

Avalere found that 40 percent of people who enrolled in earn up to nearly $18,000 a year and another 25 percent earn nearly $30,000.

On the other hand, only 8 percent of people who earn up to $44,000 a year signed up through, which covers 37 states, and only 2 percent earned $60,000 or more.
