As you may have suspected, the Medicare-style public option that you thought you were fighting for isn't the same "public option" that's coming out of committees in the Senate and the House. Not even close.
In a must-read diary at the Physicians for a National Health Program blog, Kip Sullivan describes how Congressional Democrats, and even some progressive groups, are using a classic bait-and-switch to redefine the public option and sell us a useless watered-down version:
According to the Congressional Budget Office, the "public option" proposed in the House "tri-committee" bill might insure 10 million people and would leave 16 to 17 million people uninsured. The "public option" proposed by the Senate HELP committee, again according to the Congressional Budget Office, is unlikely to insure anyone and would hence leave 33 to 34 million uninsured. The CBO said its estimate of 10 million for the House bill was highly uncertain, which is not surprising given how vaguely the House legislation describes the "public option." [...]
Obviously the "public option" in the Senate HELP committee bill (zero enrollees; 34 million people left uninsured) and the "public option" in the House bill (10 million enrollees (maybe!); 17 million people left uninsured) are a far cry from the "public option" originally proposed by Professor Hacker (129 million enrollees; 2 million people left uninsured).
Go read Sullivan's diary to understand how the original public option is nothing like what's coming out of Congress, including the one drafted by the Senate HELP Committee.
