ORLANDO, Fla. (AP) – President Obama’s top health official is back in Florida to discuss the Affordable Care Act. Enrollment has been much smoother since year two kicked off last month. Federal health officials say 85 percent of Florida’s current enrollees could obtain coverage for $100 or less after tax credits in 2015. First-time buyers and those re-enrolling from last year only have until December 15 if they want their coverage to start on Jan. 1. The enrollment period ends Feb. 15. Secretary Sylvia M. Burwell’s visit Tuesday at an Orlando hospital marks several recent stops for her in the Sunshine State, which led enrollment last year among the 36 states relying on the federal exchange with nearly 1 million sign-ups. Most of those enrollees received a tax credit to help with costs.
