John Conyers (D-Michigan) was not happy last night with his colleagues Charles Rangel (D-New York) and Henry Waxman (D-California).

Conyers is sponsor of the single payer bill (HR 676) in the House.

The bill has 79 co-sponsors.

Rangel and Waxman were co-sponsors last year.

But they are not co-sponsors this year.

Increasingly, doctors, even conservative doctors, are moving to support a single payer national health insurance system.

That’s the take of Dr. David Himmelstein, an associate professor at Harvard Medical School and a founder of Physicians for a National Health Program.
