According to a new Gallup poll, 55% of American surveyed approve of the Affordable Care Act, the law known as Obamacare. This is the first time in Gallup's polling of the ACA that the law has cracked 50% approval since the firm began asking about the law in November 2012.

The 55% approval and 41% disapproval of the ACA represents a huge shift from just after the 2016 election. In November, Gallup found that Obamacare had only a 42% approval rating, while 53% disapproved.

The shift also comes after a number of polls have showed increasing popularity for the law, as well as the failure of the Republican Party to pass their repeal and replacement bill — the American Health Care Act — through the House. That legislation was viewed highly unfavorably, with one survey suggesting as few as 17% of Americans viewed it in a positive light.

Gallup also found that 26% of those surveyed favored keeping the ACA in place as it is. Another 40% wanted Obamacare in place with significant changes, while 30% wanted Obamacare repealed and replaced.
