Are enough young and healthy people signing up for health insurance plans through the ObamaCare exchanges to balance out the new and costlier risk pools created by older and sicker individuals more likely to be interested in doing so? We don’t know, because the White House is flatly refusing to tell us — which doesn’t seem too bode well for them (you know that they would be reveling in the release of that information if the numbers were on their side), and they certainly aren’t slowing down on their sustained PR effort to convince the all-important youth demographic that ObamaCare is just about the best thing that will ever happen to them. Via ABC:

The White House is planning to make a major play to sign up young and healthy Americans for Obamacare when the Winter Olympics open next month.

The Department of Health and Human Services will launch a TV ad blitz to take advantage of anticipated increased viewership on NBC stations which will carry the Olympic coverage between Feb. 7 and 23, an administration official confirmed to ABC News.

The official said the ads would run in markets with the highest rates of uninsured, but declined to specify the locations or the amount that would be spent.

The ads will encourage uninsured people, particularly young adults, to enroll in Obamacare coverage before the March 31 deadline.

No word on exactly how big the buy is or what the ads will look like, but it’s probably a good call on the advertising front — Wide audience? Check. High-injury extreme sports? Check. Advantageous and prolonged timing smack in the middle of the latter half of the enrollment period? Check — and it sounds like the White House is going to need it.
