The federal Obamacare enrollment window for 2017 is almost over: The federal government has cut in half the length of time people have to purchase insurance policies on the marketplace; coupled with a drastic reduction in outreach funding, that’s likely to result in lower enrollment rates compared with previous years.

Across the US, today is the last day to enroll to benefit from coverage beginning Jan. 1. A few states, however, will give their citizens the opportunity to enroll after that date, and get coverage beginning on Feb.1 and Mar. 1.
