Since the passage of the Affordable Care Act in 2010, Kaiser Family Foundation polling has found the public divided in their overall views of the law and in the intensity of their opinions: For seven years, the share of the public holding strongly unfavorable views of the law has outnumbered the share with strongly favorable views.

A new analysis of Kaiser Family Foundation polling data finds that intensity gap started to close in spring 2017, as Congress began debating repeal. The share with a “very favorable” view of the law began rising in April, and is now roughly equal to the share with a “very unfavorable” view (about three in 10 in the four most recent polls).
