WASHINGTON — President Donald Trump says it’s probably time to “just let ObamaCare fail” after the latest humiliating heath bill collapse in the Senate. Still, he’s making a last-ditch effort to find some way to revive his party’s seemingly failed efforts on the bill.

Trump stayed largely on the sidelines as Majority Leader Mitch McConnell struggled unsuccessfully to round up support to make good on the GOP’s years of promises to repeal and replace former President Barack Obama’s health care law. But with McConnell’s third and final effort — on a repeal-only bill — looking like it, too, had collapsed, Trump urged McConnell to delay a make-or-break vote until early next week.

And the president invited all GOP senators to the White House for lunch today to discuss a path forward.

Trump pulled a similar move in June after McConnell fell short on his first health care effort, and it yielded no apparent results. Indeed Trump seated himself between two GOP senators — Susan Collins of Maine and Lisa Murkowski of Alaska — who announced Tuesday they would oppose McConnell’s efforts to move forward with the latest bill.

Along with opposition from a third GOP senator, Shelley Moore Capito of West Virginia, that was enough to kill the legislation. McConnell can lose only two votes and still move forward in the closely divided Senate.

It looked like after seven years of campaigning on the issue, Republicans had discovered once in power that their own divisions would prevent them from delivering. McConnell was ready to hold the showdown vote today, to get senators on record on the issue and move on to other priorities like overhauling the tax code. But in a closed-door GOP lunch, fellow Republican senators urged him to wait, according to Republicans present who demanded anonymity to discuss the private issue. McConnell announced late Tuesday that the vote would occur early next week, “at the request of the president and vice president and after consulting with our members.”

Yet with Murkowski, Collins and Capito already on record as “no” votes, and others harboring private reservations, it’s not clear what can change over the next several days. Trump himself earlier Tuesday sounded ready to move to other issues.

“I think we’re probably in that position where we’ll just let ObamaCare fail,” the president said. “We’re not going to own it. I’m not going to own it. I can tell you that the Republicans are not going to own it. We’ll let ObamaCare fail and then the Democrats are going to come to us and they’re going to say, ‘How do we fix it?’”

Despite the current law’s problems, most health care experts do not believe it is at immediate risk of outright failure, and Democratic cooperation to adjust the law is far from assured.

Nor does it appear likely that Republicans can escape owning the problems with the law and the health care system overall, now that they control the House, Senate and White House, partly on the strength of campaigning against the law.

“They seem to have this notion that they can be a majority party, and have control of the White House, and not be responsible for bringing down the health care system,” said Democratic Sen. Dick Durbin of Illinois. “It doesn’t work that way.”
