71% of uninsured still not familiar with health care exchanges.
34% of uninsured will choose to pay the fine versus 25% in Sept.
If this is the case then I suspect that the massive traffic on Obamacare in the first week or two are people like me, those with health insurance but taking a look at prices to prepare for the day when they might not have health insurance from work. If this 34% are skewed toward the young and healthy then I the death spiral of Obamacare might be upon us if this keeps up over the next year or two.
That 34% will be skewed toward the Republican, not toward the young. It makes no sense for a young person to pay a fine when they'd have subsidies helping pay for most their healthcare anyway. And spoken from first-hand knowledge: Once someone pays a RomneyCare/ObamaCare fine once, they sign up for insurance immediately the next year.
Paying money to get nothing is dumb when you can often pay less money and get something.
