MICKEY KAUS: The GOP’s Grandfather Weapon:

I don’t quite understand the new, near-unanimous Dem line on Obamacare–which is that because it has signed up a few million people, many previously uninsured, it is now somehow invulnerable to repeal. . . .

It wouldn’t be hard for Republican repealers to write a law that got rid of Obamacare while somehow keeping those few million who’ve signed up on some form of similar insurance. “If you like your Obamacare you can keep your Obamacare.” Exchange policies could be converted to non-exchange policies in a special, no-new-enrollments program, for example. Over time, attrition would whittle this grandfathered class down to trivial size–a process with which you’d think Obamacare’s architects would be familiar.

You’d think.
