“It wasn’t until the repeal-and-replace debate that some of the real benefits of the law became clear to people,” said Mollyann Brodie, a senior vice president at the Kaiser Family Foundation, referring to congressional Republicans’ efforts in 2017 to repeal and replace the law. “Given our experience of what we observed during repeal and replace, I think that it’s certainly the case that when people feel like there is a real threat to this law, there is a real rallying-around-the-law effect.” The March numbers were just released this week, showing an overall net favorability of about +10, but Brodie said they expect to see a bump in favorability if the Trump administration renews its efforts to dismantle the ACA.

In fact, since 2016, support for the law has increased significantly across every demographic group KFF tracks with one notable exception — people that identify as Republicans.2 Trump campaigned on repealing Obamacare, so renewed efforts to repeal the law could be a play to his base.
