Sarah Palin said McCain's health care tax credit is budget neutral. That is NOT true. There is currently no budget estimate of the cost of McCain's plan, much to the consternation of McCain's top domestic policy advisor, Douglas Holtz-Eakin, the former head of the (estimating agency) Congressional Budget Office.

UPDATE: The Urban Institute-Brookings Tax Policy Center estimates the McCain plan would cost $141 billion in 2013.
