Dems scramble after warning from health insurers
---
I guess the Dems now know that they need to put more cost container into the measure since the insurance companies are already planning massive cost increases, but other than that - which was needed anyway, why should Democrats "scramble"?
Does anyone think that the insurance companies are going to be truthful at this point?
