Yesterday, the Washington Post ran an op-ed by Martin Feldstein that falsely claimed that President Obama supports a British-style health care system in which “the government owns the hospitals and the doctors are salaried.”

It was a glaring and obvious falsehood based on Feldstein's incorrect definition of the phrase “single-payer.” The kind of thing that is so obviously false, it shouldn't have taken the Post more than 30 seconds to write up a correction once the mistake was pointed out. And the mistake was explained by The New Republic's Jonathan Chait by mid-day yesterday, and by Paul Krugman later in the day. But the Washington Post has not yet run a correction, online or in print.

In case the Post hasn't noticed, the health care debate is kind of a big deal right now. Correcting this obvious falsehood as soon as possible is the only responsible thing to do.
