Andrea Mitchell to Sen. Bernie Sanders, moments ago:

“Why is this so important? Is it better to have nothing than to have a plan that does not include the public option?”

It seems to me that framing -- a choice between nothing and what liberals want -- is common, while conservatives don't face such questions in the health care debate.

So here's a challenge for Andrea Mitchell: The next time you interview a Ben Nelson or a Joe Lieberman or a Mary Landrieu or a Chuck Grassley, ask them “Is it better to have nothing than to have a plan that includes the public option.”
