Support among Republican voters for the repeal of Obamacare has fallen substantially over the past month.
According to a McClatchy-Marist poll, support for health care reform dropped from 68 percent among Republicans to 57 percent.
The result came a week after a House vote on the American Health Care Act, the reform proposal backed by President Donald Trump and House Speaker Paul Ryan, was pulled without a vote.
"These Republican numbers suggest at the base there has been some erosion," said Lee Miringoff, director of the Marist College Institute for Public Opinion, McClatchy reported. "Times have changed."
Only 17 percent of voters back Ryan's American Health Care Act. By contrast, the poll found that 65 percent of respondents want Obamacare to be strengthened or maintained.
"In terms of the notion of 'repeal and replace,' a repeal is only acceptable if the replacement is actually an expansion, not a contraction," Miringoff added.
The poll was conducted between March 22 and March 27. The Republicans' failed bid to repeal and replace Obamacare occurred March 24.
Reports are circulating that Republicans may try to revive the bill, with the possibility of a vote on the measure next week being discussed. However, no date has been fixed for this.
Two Republican lawmakers told Bloomberg that the party's leadership was considering organizing a vote, even if it means staying over the weekend.
"This is not the end of the debate," Republican Sen. Mark Meadows said, according to The Hill. "We may be in overtime, but I can tell you at the very end of the day, the most valuable player will be President Trump on this, because he will deliver. He's committed to the American people."
Meadows is chair of the conservative Freedom Caucus, which said it would have voted against the health care reform bill.
He refused to commit to a timetable for a new vote.
"There's a real commitment among members he's been speaking with to not give up and move expeditiously toward a path forward," Alyssa Farah, Meadows' spokeswoman, told Bloomberg. "But he doesn't want to constrain himself to artificial deadlines like before recess."
Reince Priebus, Trump's chief of staff, also did not rule out returning to the issue.
"Everything is on the table," Priebus said, according to The Hill. "We'll give these guys another chance."
He urged Republicans to strike a compromise.
"We can't be chasing the perfect all the time. Sometimes you have to take the good, and put it in your pocket and take the win," he added.
