So what can we actually expect Congress to do about Obamacare when the House and Senate come back next month? I've heard a couple of things in recent weeks that should help paint a picture of the challenges any bipartisan bill will face.

First, one health care lobbyist who had spoken recently with Republican staff told me there's a real fear that if Congress were to pass a bill to stabilize the Obamacare markets, President Trump would veto it.

Then at a briefing I attended with congressional health staffers earlier this week, the discussion ended with speculation about whether a package could be put together with enough support to override a presidential veto.

"Presumably what the [Senate health] committee is working on, if it is truly bipartisan, could potentially make the president’s signature irrelevant," one senior Democratic aide said. "Just depends on how many people you have supporting it."

So we are off to a great start.

But another factor complicates this even further: Cassidy-Graham-Heller, the last plan standing to repeal and replace Obamacare.

The hope for any actual action in September — and there is abundant skepticism around Washington that such action is possible — depends on many conservatives at the Capitol letting go of their Obamacare repeal dreams while at least one plan to overhaul the law is still drawing breath. The proponents of a bipartisan solution will have to convince them to set that aside and come into the fold.

The Senate health committee has made clear, in its choice of witnesses for hearings on September 6 and 7, that members really are seeking some third way forward on the law.

Governors from Massachusetts, Ohio, Tennessee, Utah, and Colorado will attend. Four Republicans and one Democrat. Three Medicaid expansion states and two non-expansion states. It's as centrist as you can get. Those same traits can be found in the state insurance commissioners who were asked to attend.

But transitioning suddenly — and on a tight timeline, with action likely needed before a late September deadline for the 2018 Obamacare marketplaces — from the scorched-earth partisan warfare of the past seven years to some kind of bipartisan compromise is going to be a huge concession for conservatives.

That's why Cassidy-Graham, which Sarah explained in great detail, is lingering. GOP leadership has shown no interest, but the rank-and-file conservatives who campaigned for years on repealing Obamacare know it's still out there, and they're curious.

As Sen. Bill Cassidy (R-LA) rightly put it, it's "the only game left in town." The Freedom Caucus chair is interested. So is the White House, where Trump still hasn't let go of the failure of Obamacare repeal, as he reminded us just yesterday.

We’ve even picked up on rumors that the senators are trying to get their ducks in a row for an early September rollout of Cassidy-Graham — the very same week that the health committee is holding its stabilization hearings.

Here's my point: Serious people in Washington are already talking about the possibility that a stabilization bill needs to be veto-proof. It's going to be hard to win such an overwhelming majority — two-thirds of both the House and the Senate — when you still have this distraction that promises a path toward repeal.

Or to put it in one image:

Chart of the Day

Somebody alert Dean Heller. The left-leaning CBPP did its best to evaluate Cassidy-Graham, using what we know about the not-quite-yet-finalized bill and previous CBO estimates. The chart tells the story: deep cuts to health care spending, including Medicaid. Which makes it all the stranger that Sen. Dean Heller (R-NV), who opposed previous Republican bills over Medicaid cuts, has lent his support to this plan.
