Obamacare can stay

..if these people pay.
Will the new enrollees pay their premiums?
Megan McArdle wonders as she waits for good numbers.
Start with what we know about these people: They waited until the last minute to sign up. This tells you that a lot of them will fall into one of a few groups:

1. People who are incredibly disorganized.
2. People who are so financially pinched that it was important to wait until the last minute so that they could pay eight months' worth of premiums instead of 12.¹
3. People who are young and healthy enough to make acquiring insurance less than urgent.

The fate of Obamacare lies in the hands of enrollees paying their premiums.
When you say your program is "paid for," it means all of these people will pay their monthly premiums.
For years to come.
