From the NYT Caucus blog:

Sen­a­tor John McCain’s top domes­tic policy adviser, former Con­gres­sional Budget Office direc­tor Dou­glas J. Holtz-​Eakin, recently said in a con­fer­ence call with reporters that Mr. McCain’s health care pro­posal would “put 25 to 30 mil­lion indi­vid­u­als out of the ranks of the unin­sured, into the ranks of the insured.” In an arti­cle released Tues­day, a panel of promi­nent health econ­o­mists con­cludes that Mr. Holtz-Eakin’s pro­jec­tion is off by, well, 25 to 30 million.

The arti­cle, pub­lished in the jour­nal Health Affairs, argues that “ini­tially there would be no real change in the number of people cov­ered as a result of the McCain plan.” After a short-​term reduc­tion of 1 mil­lion in the number of people with­out cov­er­age, the number of unin­sured would increase by 5 mil­lion after five years, the authors predict.
