Obamacare versus Canadacare

From Social Science Research Network:

Using recent survey data, this article examines how Canadians compare with insured Americans and uninsured Americans in their level of satisfaction with their health care. The data reveal that the vast majority of Americans, whether insured or uninsured, get timely access to quality care and are satisfied with it. It further finds that for most comparisons, Canadians are experiencing satisfaction levels much closer to that of America’s uninsured than they are to America’s insured.

If we enact Obamacare, how many millions of Canadians will be left without a health care safety net when they can't get timely care in their own country.
