A news analysis in the NYT by Jennifer Steinhauer argued that Republicans were rediscovering an old truth in their effort to repeal the Affordable Care Act, that it is hard to take away benefits that the government has given. While the point is surely right, the piece left out an important point, the Republican effort was based on a lie.
Republicans, and especially President Trump, rallied public support for repeal of the Affordable Care Act (ACA) based on the complaint that it wasn't generous enough. They argued that the premiums and deductibles were too high, their plan would give people better insurance.
This was a complete lie, but many people who had legitimate complaints about ACA likely backed Trump and other Republicans with the expectation that they would give them better insurance. Since this is clearly the opposite of what repeal is about, it makes it especially difficult for the Republicans to tell the people who voted for them expecting better insurance that they will have to pay much more money for worse insurance.
This is the situation the Republicans now find themselves in. Essentially, they have to own up to the fact that they have been lying for seven years about the central item on their political agenda.
