After a decade of trying to gut Obamacare, Republicans may finally get their wish thanks to a Trump administration-backed lawsuit. Its success would cause chaos not only in the insurance markets but on Capitol Hill. And Republican senators largely welcome it — even if they don’t know what comes next.

“I’m ready for it to succeed,” said Sen. Mike Rounds (R-S.D.). “I would love to get back in and actually deal with health care again.”

“Do I hope the lawsuit succeeds? I do,” said Sen. Kevin Cramer (R-N.D.). “What I wish is we had some idea where we are going if it does succeed, as it looks more and more like it might.”

Even Republicans not known for taking a hard line are eager for a forcing mechanism to take on Obamacare.

“I have a plan that I would be delighted to have Congress pick up and go forward with,” added Sen. Mitt Romney (R-Utah) of a proposal to protect pieces of the law. “Necessity is the mother of acceptance. I hope that we reach that necessity and that would propel my proposal to see a good deal of support.”
