Twice as many people bought guns on Friday as signed up for health insurance.
I've confirmed exactly 2,272,733 QHP selections nationally as of yesterday, but that only runs through last Saturday, while some states are missing entirely. My best guess as to the actual total as of 12/02/15 (32 days into the 2016 Open Enrollment Period) is around 3.14 million. That's an average of around 98,000 people per day signing up for private health insurance so far.
The National Instant Criminal Background Check System processed 185,345 requests on Nov. 27, one of the largest retail sales days in the country.
NOTE: Actually, ACA exchange signups were likely far lower than 98K on Friday; enrollments tend to drop off substantially on holidays (and post-holidays). Technically speaking, it was probably only around 20K apiece on Thursday and Friday specifically. However, if you're seriously focusing on that instead of the fact that we're drowning in firearms, you're missing the damned point.
