There's a lot out there that you've no doubt read about the difficulties for Republicans in actually repealing the Affordable Care Act. Surprise, surprise: It's not as easy as saying "Public Law 111-148, as amended, is hereby repealed." (Gotta have that "hereby.") One problem (among many): People may not like "Obamacare" in the abstract — and that view may not be as widely held as it used to be — but a lot of them like its key provisions.
And when former Speaker of the House John Boehner says that a quick repeal and replacement of Obamacare is just "happy talk" and "most of the framework of the Affordable Care Act … [is] going to be there" after all is said and done, that may tell you something.
