I think that the website at Healthcare.gov was a fake. I think that CGI did build a website framework and it was programmed. But, sold to another buyer. The website the government wound up with wasfake and was compatible with Windows and Internet Explorer, (older systems). I got the same action on Blogger. Blogger breaks down when you use Chrome without Firefox. But works OK with Windows 7 and Explorer. (Like that.)
The website Healthcare.gov might have been a fake that was never meant to go online. I now believe that it was a fake.
If there was a real website it was built for another system.
