To Democrats, the case against the Republican health care bill is simple. The Congressional Budget Office has found, on more than one occasion in assessing more than one version of the proposal, that it will leave far fewer Americans with insurance coverage than under the Obamacare status quo. Republicans have countered that the CBO has been wrong before and that its assessment of the bill is way too harsh, mostly because it greatly overstates the effectiveness of Obamacare’s individual mandate. Let’s assume for the moment that Republicans are right and that the Better Care Reconciliation Act will cover more people than the CBO projects. In that hypothetical world, we would know one thing for certain: The GOP effort to replace Obamacare would also cost far more than the CBO projects.
