Democratic presidential frontrunner Hillary Clinton on Sunday strongly defended President Barack Obama's signature health care legislation but admitted that she would propose a number of fixes to the law if she were to succeed Obama in the White House, the Hill reported.

The former secretary of state pointed to the so-called the "family glitch," which prevents some low-income families from qualifying for subsidies under the law, as an example of an item that required attention.

During the course of her 2016 presidential campaign, Clinton will propose ideas "about how to fix the family glitch, for example; about how to deal with the high cost of deductibles that put such a burden on so many working families; and (about) how to deal with the exploding cost of drugs, particularly the so-called specialty drugs," the candidate told the Des Moines Register.

Clinton, who as first lady had unsuccessfully pushed her own program for health care reform, noted that she was ready to make changes regardless of the outcome of a pending Supreme Court case. The nation's highest tribunal is mulling whether to invalidate subsidies that help 6.4 million people in at least 34 states who bought health insurance through the federal exchanges.

A 1973 Yale Law School graduate, Clinton echoed fellow Democrats in accusing the plaintiffs in King vs. Burwell of making an out-of-context claim that the phrase "established by the state" bars subsidies on the exchanges, which are not established by the individual states; that was a "very contorted argument that is being made by the opponents to blow up the Affordable Care Act's guarantee of coverage," she contended.

Clinton's comments suggest that the Democratic frontrunner "may be preparing to go on offense against Republicans" if the Supreme Court sides with the challengers, the Washington Post commented. She signaled an "aggressive engagement if and when the debate turns to what should happen next."

GOP lawmakers, meanwhile, are divided on how to respond if the justices end up doing away with the subsidies. Some Congressional Republicans have suggested that the payments could be extended temporarily, but that move is likely to draw strong opposition from the party's consevative wing.
