Input: Washington (CNN) Americans views of Obamacare tilt narrowly positive, according to a new CNN/ORC poll, marking the first time more have favored than opposed the law since its passage in 2010. The shift comes at the same time more than 8-in-10 say the law is likely to be repealed and replaced by incoming president Donald Trump. Overall, 49% say they favor the 2010 health care law, more formally known as the Patient Protection and Affordable Care Act, while 47% oppose it. Though a mostly mixed review overall, that's a sharp improvement compared with previous polling on the law. More have opposed than favored the law in every CNN/ORC poll on this question from March 2010 until now. The shift in the law's favor stems largely from Democrats and independents, while views among Republicans haven't moved much.49% say they favor the 2010 health care lawBut few feel the ACA has done much to help them personally
