Friday is the last day Iowans can sign up for healthcare coverage under the Affordable Care Act. The Centers for Medicare and Medicaid services said this week that as of December 9th, nearly 28,600 Iowans had signed up for Obamacare coverage. That's an increase of more than 6,000 signups since December 2nd. People who want to sign up have until the end of Friday to do so in order for healthcare coverage to start on January 1st.
