President Trump has, thus far, been unsuccessful in repealing the Affordable Care Act, commonly referred to as Obamacare.
Nonetheless, a recent The Economist/YouGov poll found that 31% of Americans believe he did, and 21% aren't sure. 
That leaves just under half giving the correct answer. 
The poll involved 1,500 participants and was conducted from December 24 to 26, just days after the passage of the GOP tax bill. 
Some of the confusion may have come from the part of the legislation to put an end to the individual mandate, which penalizes those who do not have health coverage. 
The issue may have been further clouded by some of Trump's tax bill related statements. 
"The individual mandate is being repealed. When the individual mandate is being repealed, that means Obamacare is being repealed because they get their money from the individual mandate," Trump said at a December 20 cabinet meeting.
During the December 22 bill signing, Trump noted, "We've essentially repealed Obamacare. You know, the individual mandate is a very big factor in this bill, frankly." 
According to an Associated Press fact check, those statements aren't accurate. 
"The fines on people who don't carry health insurance only provide a small fraction of the financing for the program," notes the news agency.
Further, Obamacare's other requirements, including the expansion in Medicaid availability, price protections for people with pre-existing conditions, and giving subsidies to those who need help covering their premiums, still stand.
