Some sound almost resigned to the new reality. “I’d say it’s 50-50,” Rep. Kevin Cramer (R-N.D.) said of the prospect the law will remain in place.

Republicans are torn between the potency of their longtime rallying cry against Obamacare — so popular with GOP donors and their base that it helped flip both houses of Congress and the White House — and the reality they’ve wasted nine months of what is supposed to be the most productive time of a new administration failing to get it done. With few legislative accomplishments so far to show voters, failure on Obamacare repeal could prove to be a major liability in the 2018 midterm elections.

Even if Republicans try again next year, few House Republicans are confident the Senate would be successful without a change in the GOP lineup or someone flipping their vote.

“Anytime you fumble twice, there’s the anticipation that you’ll fumble for the third time,” said Rep. Mark Meadows (R-N.C.), chairman of the conservative House Freedom Caucus. Do Senate Republicans have “credibility? Yes. Believability? Perhaps no.”

Nearly every Republican interviewed for this story insisted they still oppose the health care law and want to see the repeal effort move forward. But the failure to gather 50 Senate votes before the Sept. 30 deadline to pass a bill without the chance of a Democratic filibuster has injected a new dose of realism — and political vulnerability — into their ranks. Once-lofty campaign promises to tear out Obamacare “root and branch,” as Senate Majority Leader Mitch McConnell said throughout his 2014 reelection campaign, are as likely to produce winces as cheers.

“I would bet a substantial part of it is there 10 years from now,” said one GOP senator, who declined to say that for attribution.

After last month’s latest failure on the repeal bill drafted by Sens. Bill Cassidy (R-La.) and Lindsey Graham (R-S.C.), Senate Republicans quickly turned to tax reform, saying that they planned to renew the repeal push in early 2018. Their plan, they say, is to use the same Graham-Cassidy repeal bill and renew the authority to bypass a Democratic filibuster.

The odds of success get better if Republicans can deliver on tax reform, Cramer of North Dakota predicted. A win there could build political momentum — and also foster some badly needed trust between the House and Senate.

If Republicans try for Obamacare repeal again in 2018, the House would again have to go first on a bill passed under the fast-track reconciliation process, only to risk being hung out to dry again by the Senate.

A successful tax reform bill “would be the demonstration that [senators] are serious and they can function,” Cramer said. “There would be enough optimism to give them another chance and maybe even give us all a better” shot.

For now, Republicans are wrestling with how to talk about Obamacare repeal with their constituents. For seven years, their talking points never changed: Elect Republicans and we’ll repeal Obamacare.

House Republicans, who successfully voted to repeal the law, are laying the blame on the Senate.

“I’m one guy out of 535,” Roe said. “I’ve done all I can do, and so has everyone in” the House.

In the Senate, Republicans describe how they are caught between their aspirations and the reality of a divided chamber.

“We had three chairmen go rogue,” Sen. David Perdue (R-Ga.) said of opposition from Sens. John McCain of Arizona, Lisa Murkowski of Alaska and Susan Collins of Maine, all of whom lead Senate committees — plum jobs that come with seniority and, oftentimes, an expectation of party loyalty. “The only thing I can tell voters is that we didn’t get repeal so far this year — that’s a fact.”

“I’d like to do it on the third try. I can’t guarantee it,” Sen. John Kennedy (R-La.) said. “But I can guarantee this: There will be a fourth try and a fifth try and a sixth try and a seventh try.”

The pressure for repeal is likely to mount ahead of 2018, when voters will measure whether campaign promises have been upheld.

“That’s in large part what they’re going to be voting on — that involves not just health care but tax reform as well,” said Sen. Cory Gardner (R-Colo.), chairman of the National Republican Senatorial Committee, the Senate Republican campaign arm.

The authors of the latest repeal bill, Graham and Cassidy, say they will try to build a case for repeal before early next year.

“I’m not a guy to quit,” Cassidy said shortly after a meeting with the White House to discuss his bill recently, after the vote was canceled.

For now, Senate Republicans still eager to move on repeal are hanging their hope on the lukewarm support Murkowski gave to the policy in the Graham-Cassidy repeal bill. Murkowski has said she likes the idea of block grants to the states but couldn’t get over the rushed process and the lack of key data before the vote would have had to be held.

In addition, a New Jersey Senate seat could flip from Democratic to Republican hands if Sen. Robert Menendez is convicted of corruption charges and expelled from the Senate. Republican Gov. Chris Christie would have to appoint his replacement, another likely vote in favor of repeal.

“The pain in the individual market will continue to ratchet, since I do think that the employer penalties … will continue, there will be a continued push to try to address” Obamacare, Cassidy said. “If events dictate we get another crack, we’ll be ready.”
