False. Does not square with the fact that the uninsured rate fell dramatically only after the exchanges opened, despite job creation comparable to the year before.
Please stop making things up and look at the data. When the exchanges opened, the unemployment rate rose by about 2% as millions of people received cancellations, and then it dropped 2.5% as all of those people scrambled to get onto the exchanges. The ~.5% are the new enrollees. They represent approximately 20%-25% of all enrollees.
Gallup begs to disagree with you:
First off, 0 people were thrown off ACA uncompliant plans in 2013. I repeat, zero, ZERO. This is because the ACA mandates did not take effect until January 1, 2014. The people who received the cancellation notices were still insured until the end of 2013. So obviously, that can't explain the spike.
Not to mention, the spike began in the first quarter of 2013, well before any of these cancellation notices even began arriving.
Not even mentioning that this data does not include the March/April surge, which has the uninsured rate going down another 2% to 13%.
Regarding your second point, if you REALLY want to go down that route, fine- just be sure to count the 5-7 million extra off-exchange enrollments in your total- that's where most cancelled policyholders went anyway.
So once again, your initial claim was false.
