How successful was the Patriot Act? Without measurable benefits we can't really say. For the ACA, the numbers I'm seeing are much less than 50%. From the Kaiser Family Foundation "While uninsured rates decreased across all income groups from 2013 to 2016, they declined most sharply for poor and near-poor people, dropping by 9.7 percentage points and 11.4 percentage points, respectively." From that same source "In 2017, the uninsured rate reversed course and, for the first time since the passage of the ACA, rose significantly to 10.2%." You bring to the table an important point, though. We need measurable benefits. The fact that there's even guessing at the purpose of bills shows the flaw. We should require goals with every bill. Without that we just have bickering on specifics which, by design, have never been communicated. Politicians use this lack of information to their advantage.
