I believe the prohibition applies to “private insurance,” which will be driven out of the market in favor of “public” insurance that will provide mandatory coverage of abortions.
A lot of liberals are praising the downfall of all these insurance companies. The truth is — there will be a few still around... those companies who have lobbied for this to reduce their competition and get in bed with the gov’t. I’ll bet you and I can guess which companies those will be (Kaiser Permanente, Blue Cross/Blue Shield, and maybe a few more of the HUGE companies).
[However, I may be wrong about BCBS because they issued a study on their website a few days back detailing how this will negatively affect their providers, and clients... The executives at BCBS are most likely NOT in favor of this.]
