This morning, the Congressional Budget Office released a report arguing that the partial repeal of Obamacare being contemplated by Republicans would wildly increase the number of people without health insurance, in ways that are difficult to understand. Here are four problems with the CBO’s analysis.

1. The CBO’s estimates assume no Obamacare replacement

2. The CBO massively overestimates the impact of Obamacare’s individual mandate

3. The GOP repeal bill is likely to treat Medicaid differently than the CBO does

4. CBO’s 2010 estimates of Obamacare’s coverage expansion were off by more than 10 million
