According to a new government report, Obamacare premiums are set to soar an average of 22 percent for the benchmark silver plan in 2017. The price hike is just the latest blow to Obamacare. Insurers are raising prices and downsizing their presence on the exchanges. They want to stem losses from the sicker-than-anticipated customers. Enrollment for next year will be closely watched, since insurers want younger and healthier consumers to enroll. Around 10.4 million people were enrolled in Obamacare plans as of June 30. An administration official said Obamacare enrollment is expected to grow 9 percent in 2017.
