Some 32 million more people would be uninsured by 2026 if Obamacare were repealed under a new bill unveiled by the Senate Wednesday, according to the Congressional Budget Office.

Even more stunning, three-quarters of the nation would live in areas with no insurers participating in the individual market by 2026 -- leaving many without an option if they did not have employer-provided or government health insurance.

Also, premiums would about double by 2026.

The bill would effectively repeal Obamacare in 2020, giving lawmakers until then to come up with a replacement plan. But it would also eliminate the individual and employer mandates retroactively to 2016, and get rid of taxes on the wealthy and others. It would eliminate Medicaid expansion starting in 2020.
