The quote refers to "single digits" and it is ridiculous. If even close to 20 million people tried to sign up then that means many millions of citizens need this coverage and will likely end up getting it because having health insurance is critical to their livelihood. Am I to believe 20 million people needed health insurance, got an error on the web site and just said, "forget this, being uninsured is better than dealing with a web site!"?
"The last I heard, no media outlet has been able to find a single successful sign up to interview, and they are definitely looking for one."
This is a weak argument. It is an anecdote of an anecdote which even if true would not be persuasive. Are you seriously saying that no one has signed up despite 20 million people trying (or single digits)? Your evidence is that you personally haven't found a media outlet that have themselves managed to find someone to interview? Perhaps we should wait a few weeks to make judgement after the facts are known and the government is actually running again?
