very well at times predicting things on budget, whether it's revenue or spending, i don't think it does a great job, and i think the administration has been clear and consistent that we don't always agree that it does a great job predicting coverage. >> well, clearly not a man of the cbo's work. but the criticism does seem selective. the cbo did overestimate the number of people who get their care through the obamacare exchanges, however, if she is suggesting that the cbo did a bad job overall on obamacare, other facts don't support her. the cbo estimated the loss impact on the total percentage of people with and without insurance as well as total number of people lacking insurance, and they were very close in those. in any case, after attacking the most politically toxic part of the cbo report, she did embrace others. >> and the cbo score that they pointed out was that it would cut deficits by $300 billion and taxes by $700 billion.
