Obamacare consumers will face double-digit rate hikes for 2017, with most states looking at an average 25 percent increase, according to one estimate.

The premium spikes come as the Obama administration will boost outreach this open enrollment season, which starts Nov. 1, to reach more people who are uninsured. Opponents of the law point to the premium hikes as evidence the law isn’t working, while the Obama administration said healthcare would remain affordable for most customers thanks to tax credits.
