This article from the New York Times suggests that following repeal of Obamacare, House Republicans will look for a replacement that substitutes liberty for compulsion -- a big improvement:
In defending the Affordable Care Act, the Obama administration, congressional Democrats and advocacy groups have focused on the 20 million people covered by the law, which has pushed the percentage of Americans without health insurance to record lows. The American Medical Association recently said that “any new reform proposal should not cause individuals currently covered to become uninsured.”
But House Republicans, preparing for a rapid legislative strike on the law next month, emphasize a different measure of success.
“Our goal here is to make sure that everybody can buy coverage or find coverage if they choose to,” a House leadership aide told journalists on the condition of anonymity at a health care briefing organized by Republican leaders.
. . .
Republicans have an “ironclad commitment” to repeal the law, the aide said, as lawmakers moved to discredit predictions that many people would lose coverage.
“There’s a lot of scare tactics out there on this,” said Representative Kevin Brady, Republican of Texas and chairman of the Ways and Means Committee. “We can reassure the American public that the plan they are in right now, the Obamacare plans, will not end on Jan. 20,” the day Donald J. Trump will be inaugurated.
The suggestion that 20 million people will lose coverage is a “big lie,” Mr. Brady said, after meeting here with Republican members of his committee.
“Republicans,” he said, “will provide an adequate transition period to give people peace of mind that they will have those options available to them as we work through this solution.”
