Health exchange

This summer was supposed to be a time for the Obama administration to reintroduce the public to the Affordable Care Act and teach people how to sign up for benefits this fall. But despite another White House speech, that's not happening. And an expert in political messaging thinks he knows why.

The nonprofit Enroll America wants to encourage uninsured Americans to sign up for the exchanges when the time comes. Though the group has support across industries and from the Health and Human Services secretary, it's still been hit by congressional controversy.

The next move in the health care law is all about coverage for people who don't have health insurance. President Obama has been trying to clear up some of the confusion over who gets coverage, and when. But many questions remain to be answered.
