The Note: 'Kimmel test' challenges Republicans on health care Republicans will have to own the policy as well as the process of health care.

 -- THE TAKE with ABC News' Rick Klein

Maybe it's been a long, long time, but this science isn't so hard to understand. The medical groups ... the bipartisan governors ... the Congressional Budget Office ..."essential health benefits"... Lisa Murkowski and Susan Collins and John McCain ... legislative deadlines ... Mike Pence ... Jimmy Kimmel. Oh, yeah, Kimmel: "They're not taking care of you. They're taking care of the people who give them money," he said on "Jimmy Kimmel Live!" Tuesday night. "This guy Bill Cassidy just lied right to my face." The previous rounds on health care have broken through publicly and politically, so much so that Obamacare's popularity soared to new heights. This rerun of the fight has been quieter, to the GOP's benefit so far. But, as Democrats learned the hard way in the Obama years, Republicans will own the policy as well as the process. GOP leaders have cleared the way for this, even cutting off bipartisan talks around market stabilization to make Graham-Cassidy the only option left. But pursuing their promise under a procedural rush-job won't end the discussion. Sept. 30 is the deadline for action, though there will be no expiration date on the consequences.

WHAT WOULD THE BILL ACTUALLY DO?

The Congressional Budget Office has not finished a full analysis of the Cassidy-Graham health care bill, but previous reports offer some clues. For instance, the Graham-Cassidy legislation would repeal the individual and employer mandates right away; CBO has estimated that move alone would result in about 15 million more Americans without health insurance over the next 10 years. The bill also calls for large cuts to Medicaid funding, which was one of the biggest reasons the CBO said other repeal legislation would lead to even larger numbers of Americans losing access to insurance. Those other bills still include tax credits or subsidies to help people buy insurance. That goes away here. States would get a lump sum with broad flexibility in how they spend the money. There's little guarantee that states spend it to help more people get health insurance. The bill also leaves in place waiver programs, seen in other repeal bills, allowing insurance companies to offer bare-boned plans and charge people more based on health status. The CBO has said such waivers would likely result in premium decreases for some younger, healthier Americans, but big jumps in cost for sicker Americans purchasing on the individual markets, or those who need more coverage. Bottom line: States that want to keep everyone covered under existing law would likely have to pay a lot more, and rights that an individual had to have health coverage would be gone, ABC News' MaryAlice Parks writes.

ANALYSIS: Trump launches rhetorical rockets at United Nations. Making American great again, in the view of the man who made that phrase a campaign slogan, means making the world understand that America is redefining the way it is seeking out that greatness. That means absorbing the boasts, name-calling and contradictions in President Trump's first address to the United Nations. Tuesday he lined up a series of rhetorical rockets and all but dared his counterparts in the world community to try to stop him from launching them. http://abcn.ws/2xlkCe3
