Former President Donald Trump’s renewed focus on repealing and replacing the Affordable Care Act, known colloquially as Obamacare, has alarmed some Republicans scarred by the GOP’s failure to deliver on promises to dismantle the law and who view the issue as a political loser with the American people.

Many on Trump’s team said they were surprised by the former president’s recent declaration on his social media website Truth Social that replacing Obamacare would be a priority of his administration, as Obamacare had not been a focal issue in ongoing policy conversations and the campaign has not yet drafted any kind of health care policy alternative. One Trump adviser told CNN the post came “completely came out of nowhere,” and said the team “has not been talking to him about health care.”

Some Trump advisers who spoke with CNN also conceded that calling for the termination of a health care law that provides millions of Americans coverage and is largely viewed favorably by the public is a political loser going into 2024. Republicans have tried and failed for years to implement substantial changes to Obamacare and the party has largely abandoned efforts to campaign on the issue.
