Why Are Centene And Molina The Exception To Most Big Health Plan Losses On The Obamacare Exchanges?

This paragraph in a recent AP story caught my eye:

Two companies that report exchange success so far, Molina Healthcare Inc. and Centene Corp., say they have focused on covering low-income customers in markets where they already have an established presence in Medicaid, the state-federal kegiatan that covers the poor. Molina sells coverage in nine states and is thinking about adding two for next year.

Why are these traditionally Medicaid carriers doing so well when most of the health plan market is losing their shirts in the Obamacare exchanges?
