House Speaker Paul Ryan walks to the House Chamber to vote on Obamacare repeal, on Capitol Hill in Washington on Jan. 13, 2017.

(WASHINGTON) — Ascendant Republicans drove a budget through Congress on Friday that gives them an early but critical victory in their crusade to scrap President Barack Obama’s health care overhaul.

The vote trains the spotlight on whether they and Donald Trump can deliver on repeated pledges to not just erase that statute but replace it.

Demonstrating the GOP’s willingness to plunge into a defining but risky battle, the House used a near party-line 227-198 roll call to approve a budget that prevents Senate Democrats from derailing a future bill, thus far unwritten, annulling and reshaping Obama’s landmark 2010 law. The budget, which won Senate approval early Thursday, does not need the president’s signature.

“The ‘Unaffordable’ Care Act will soon be history!” Trump tweeted Friday in a dig at the statute’s name, the Affordable Care Act. Trump takes the presidential oath next Friday.

But the real work looms in coming months as the new administration and congressional Republicans write binding legislation to erase much of the health care law and replace it with a GOP version. Republicans still have internal divisions over what that would look like, though past GOP proposals have cut much of the existing law’s federal spending and eased coverage requirements while relying more on tax benefits and letting states make decisions.

Friday’s final vote was preceded by debate that saw hyperbole on both sides and underscored how the two parties have alternate-universe views of Obama’s overhaul. Democrats praised it for extending coverage to tens of millions of Americans, helping families afford policies and seniors buy prescriptions, while Republicans focused on the rising premiums and deductibles and limited access to doctors and insurers that have plagued many.

House Speaker Paul Ryan, R-Wis., said the health care law was “so arrogant and so contrary to our founding principles” and had not delivered on Obama’s promises to lower costs and provide more choice.

“We have to step in before things get worse. This is nothing short of a rescue mission,” Ryan said.

“Our experimentation in Soviet-style central planning of our health care system has been an abject failure,” said freshman Rep. Jodey Arrington, R-Texas.

House Minority Leader Nancy Pelosi, D-Calif., said Ryan was peddling “mythology” and said the GOP was moving toward making things worse for health care consumers.

“They want to cut benefits and run. They want to cut access and run,” she said of Republicans.

“This is a sad day in the history of this country as Republicans begin the process of destroying health care in America,” said Rep. Hakeem Jeffries, D-N.Y., who said the GOP has no replacement in hand.

“All you have is smoke and mirrors, and the American people are getting ready to get screwed,” he said.

Approval of the budget means Senate Democrats won’t be allowed to filibuster the future repeal-and-replace bill — a pivotal advantage for Republicans. They control the Senate 52-48, but it takes 60 votes to end filibusters, which are endless procedural delays that can scuttle legislation.

Congressional Republicans have made annulling Obama’s law and replacing it a top goal for the past seven years. GOP rifts and an Obama veto prevented them from achieving anything other than holding scores of votes that served as political messaging.

Trump also made targeting Obama’s statute a primary target during his campaign. At his news conference Wednesday, Trump — who’s supplied few details of what he wants — said his emerging plan will be “far less expensive and far better” than the statute.

Despite their conceptual unity, plenty of Republicans have shown skittishness in recent days about the political repercussions of charging into a battle that, with Trump in the White House, puts enacting new laws within reach.

Many congressional Republicans expressed opposition to leaders’ initial emphasis on first passing a repeal bill and then focusing on a replacement — a process that could produce a gap of months or longer. Trump has also pushed Congress to act fast.

Twenty million Americans are covered by Obama’s expansion of Medicaid or by policies sold on exchanges, and millions of others have benefited from the coverage requirements It has imposed on insurers. Many Republicans have insisted on learning how their party will re-craft the nation’s $3 trillion-a-year health care system before voting to void existing programs.

There are internal GOP chasms over Republican leaders’ plans to use their bill to halt federal payments to Planned Parenthood and pare Medicaid coverage. There are also disagreements over how to pay for the GOP replacement, with many Republicans leery of Ryan’s proposal to tax part of the value of some health insurance provided by employers.

Even with their disputes, the GOP’s rallying behind their budget spotlighted the political imperative facing Republicans to deliver on a battle cry that has sustained them for years.

Moving ahead on the budget was “a bottom-line, party survival vote,” said Thomas P. Miller, a health care authority at the conservative American Enterprise Institute.
