CHICAGO (AP) -- Millions of Americans will be able to shop for the first time Tuesday on the insurance marketplaces that are at the heart of President Barack Obama's health care overhaul.
They will be entering a world that is supposed to simplify the mysteries of health coverage but could end up making it even more confusing, at least initially.
It might finally start to become clear whether consumers will be pleased with the experience and the premiums they will pay to get insurance. Tuesday's rollout comes after months of buildup in which the marketplaces, also known as exchanges, have been both praised and vilified.
Glitches are predicted and there's a risk: If people become frustrated and turn away from the program, the prospects for Obama's signature domestic policy achievement could dim.
