This episode of The Motley Fool's Market Checkup is all about Obamacare. Market Checkup gives a full examination of the state of the Affordable Care Act on the eve of the opening of its state-based insurance exchanges.

In this video, health-care analysts David Williamson and Max Macaluso discuss the newly disclosed average premiums available on the insurance exchanges. Many were predicting doom and gloom, but prices have come in under the Congressional Budget Office's estimates. Watch and find out which states offer the lowest premiums, what is needed to make the exchanges viable, and why WellPoint is acting more aggressively than its big managed-care counterparts.
