Lawmakers on Capitol Hill have only a short window of time to vote on the latest Republican legislation to gut and replace the Affordable Care Act, and if the GOP is going to push forward with a vote on this bill they will likely have to do so without having an idea of how many Americans will be affected, or what impact it might have on insurance rates.

The nonpartisan Congressional Budget Office is currently attempting to put together a score for the so-called “Graham-Cassidy” bill in the Senate. CBO scores on previous repeal bills provided legislators and the public with estimates on how the proposals would affect the number of uninsured Americans, insurance premiums and other costs, and the overall effect on the federal budget.
