Obamacare premiums in 2019 will be 6 percent higher because of actions by the Trump administration that many Democrats say amount to “sabotage” of the healthcare law, according to a new analysis.

Nationwide premiums for the 2019 coverage year are expected to either slightly decline or only go up by modest single digits. But premiums for all plans sold on Obamacare’s insurance exchanges are expected to be 6 percent higher next year because the Trump administration did not expand access to cheaper plans, according to the analysis released Thursday from the research firm Kaiser Family Foundation.
