A new S&P Global Ratings report finds that between 6 million and 10 million people would lose health insurance coverage if a Republican proposal to replace the Affordable Care Act becomes law.

The top end of those losses, or 10 million people, is equal to half of the 20 million or so people who have gained coverage in the past seven years under Obamacare.

A new Monmouth poll, conducted just before House Republicans revealed their new health care legislation, found that 51% of Americans said they would prefer to keep the Affordable Care Act and work to improve it, with another 7% saying they want to keep the ACA entirely intact.

Just 39% want to see the ACA repealed, either with a replacement put in place (31%) or repealed entirely without a replacement (8%).

Jonathan Chait: “The Republican Party in its modern incarnation is incapable of writing a decent health-care bill, if we define ‘decent’ to mean both some level of technical competence as well as morally decent. That inability has been clear to the party’s outside critics for many years. Republicans have fervently denied this, and probably believed their own denials. As a result they locked themselves into a course of action that forced them to propose a bill on a deadline. They seem to have realized the impossibility of the task midway through, but, unable to retreat on their commitment, they instead rushed out a plan that is shambolic and cruel.”

“The best indication of the quality of the plan is that it has drawn almost universal scorn from the health-care-policy community. It’s predictable that experts on the left would dislike Trumpcare. But the right seems barely any more favorable. Conservatives like Peter Suderman, Philip Klein, Bob Laszewski, and Avik Roy, who have spent years savaging Obamacare, are united in their disdain for its replacement.”

The Hill: “Outside conservative groups on Tuesday blasted House Republicans’ newly unveiled health care proposal, saying it doesn’t live up to the GOP’s promise of fully repealing Obamacare.”

For members: The GOP’s Last Chance to Repeal Obamacare

Playbook: “They want conservatives to relax. They say this repeal and replace bill — which, by the way, wasn’t easy to cobble together — repeals taxes, spending and mandates, reforms entitlements, strips funding from Planned Parenthood and kicks Medicaid control to the states. In other words, this is what Republicans have been asking for! The bill was penned by the committees of jurisdiction, not in the speaker’s office, which is what many conservatives have been clamoring for. Supporters believe the White House wants this bill to pass — but we’ll see how much the president leans in. From the proponents’ point of view the stakes are just too high for the GOP. Failure, they say, is simply not an option after more than a half-dozen years of promising action.”

“If Republicans can’t pass a bill, the familiar blame game will ensue. Was it because the committees and leadership were timid, as conservatives are sure to say? Or will the narrative take hold that, in the quest for the perfect, the conservatives blew up a good bill? If nothing else, Republicans will blame Democrats for not working with them.”
