Democrats ceded back the Senate floor early Tuesday morning, ending a more than 5-hour protest of GOP efforts to repeal ObamaCare.

Democrats painted the late-night talkathon as the first test against a Republican-led government as the majority party works to nix the healthcare law without a replacement plan.

"Why we're here tonight is pretty simple," Murphy — who led a 15-hour filibuster last year — said just before midnight. "The repeal of the Affordable Care Act with no replacement, with no plan for what comes next, will hurt million of real people in very real ways."

Democrats boiled down their message to Republicans using the so-called Pottery Barn rule: You break it, you buy it.

Senators repeatedly characterized the current GOP effort as "repeal and run."

"Get real, [Republicans] don't have a clue what to do next," Sen. Elizabeth Warren Elizabeth WarrenNo new taxes for the ultra rich — fix bad tax policy instead Democrats back away from quick reversal of Trump tax cuts It's time for newspapers to stop endorsing presidential candidates MORE (D-Mass.) said from the Senate floor. "Repeal and run. That's the Republican plan."

The Senate is expected to pass a shell budget resolution along a party-line vote this week that includes guidelines for repealing ObamaCare.

Democrats face an uphill battle to block the rules or the separate standalone repeal bill. Both need only 50 votes to clear the upper chamber and Republicans have a 52-seat majority.

But Democrats and outside groups appeared to take heart Monday over new signs of division among congressional Republicans.

Members of the conservative House Freedom Caucus said after a meeting at Tortilla Coast that they want more repeal details on repeal and replacement before voting on the guidelines for rolling back the law.

And another group of Senate Republicans is separately trying to kick the deadline for lawmakers to turn over their repeal proposals into early March, pushing the original Jan. 27 deadline by more than a month.

In addition to giving lawmakers more time to work on a repeal, they argue it would help lock down more details on a replacement and allow them to work with Rep. Tom Price (R-Ga.), who has been nominated to lead Trump’s Department of Health and Human Services.

The GOP senators could force a vote on their proposal on Wednesday, when the Senate is expected to hold a marathon session known as “vote-a-rama.”

Schumer told supporters on Monday night that Republicans are already getting “cold feet,” stressing that Democrats will have momentum coming off of the talkathon.

"We are winning on both sides,” he said. “They're flummoxed. We're united.”

"We have to make it clear every senator and every representative that votes to destroy healthcare in America will be responsible for disaster and consequences that come next," Warren said on the PCCC call.

Democrats warn that the floor protest and calls with outside groups are the first shot in what is shaping up to be a yearslong fight over repealing and eventually replacing the Affordable Care Act.

“We will fight this repeal with every fiber in our being,” Schumer added from the floor. “We will not go gently into that good night.”

Sanders's office noted earlier this week that more than a dozen rallies in support of ObamaCare have been scheduled across the country.

Democrats are also using social media, including Facebook Live and Snapchat, to try to build support among voters beyond the Beltway, trying to recapture the strategy that won them headlines last year on a pair of gun control protests.

The Democratic push hit a small speed bump earlier Monday, when Schumer kicked off the protest on social media by accidentally tweeting "Don't #MakeAmericaGreatAgain."

He quickly deleted the tweet and replaced it with Democratic slogan "don't #MakeAmericaSickAgain."

Sen. Cory Booker (D-N.J.) — who like Warren is getting early 2020 speculation — noted that social media can help blast Democrats’ fight against Republicans to voters across the country.

"This is exciting for me because ... maybe 10 years ago in the Senate they were often fighting with just normal things, which is you know on the Senate floor," he said on a Facebook Live video. "But we have the capacity to know to connect to people in greater ways."

As of 11 p.m. two Facebook Live videos posted by Democrats had been viewed nearly 550,000 times.
