Re: Why so many different portals to solve the same end goal?
Yes, one big debacle with Healthcare.gov -- but I guess that was finally resolved, more or less (although I haven't heard anything particularly reassuring about security) -- would have been more than enough! The answer, I think, lies in the political hash surrounding Obamacare and the related technologies. Since states have a big say in how to participate, it's not too surprising that some chose to fly solo for whatever reason. It would, however, have been much more efficient to design one national system from a technical and admin POV.
