"This may seem like same-old, same-old at this point. After all, lots of health insurers are threatening to leave the exchanges. You could be forgiven for yawning at the news that yet another company might pull back.
But in fact, this is huge news, because Anthem runs the Blue Cross/Blue Shield organizations in 14 states. And though Anthem doesn't appear to be the sole company offering exchange coverage in any of those states, the Blues are generally the backbone of the exchanges. Where others have quailed, the Blues have by and large stuck with Obamacare. If they pull out, then it’s likely that we’ll see more counties, and possibly entire states, with no Obamacare policies on offer."
