WASHINGTON — Repealing Obamacare without a replacement would result in higher costs for consumers and fewer people with insurance coverage, according to a report Tuesday from the nonpartisan Congressional Budget Office.

In the first year, insurance premiums would jump by 20 percent to 25 percent for individual policies purchased directly or through the Obamacare marketplace, according to the report.

The number of people who are uninsured would increase by 18 million.

Those numbers would only increase in subsequent years.
