Private health insurers made a Faustian bargain with Democrats in 2010: In return for supporting passage of the Affordable Care Act, the companies would be able to grow their business with subsidized customers who were required to buy insurance. How’s that working out?

Except for Dr. Faustus, not great. Democrats lost control of the House and Senate thanks in considerable part to their votes passing ObamaCare on partisan lines. And now we’re learning that private health insurers are losing money on their Affordable Care Act business, as Aetna was the latest to acknowledge on Monday during its quarterly earnings report.
