No I can't back it up because all the numbers are all over the place. Any article I post for or against can be countered with another article.
Just trying to get basic numbers on how many more are covered is impossible. I seen one article about the number of policies that were canceled. What they didn't tell you is that x amount was canceled and y of those were replaced with no loss in coverage.
The same go in the opposite direction. You see numbers of people covered by Obamacare but the numbers don't show that they have losses in coverage as a result of their having needed to switch plans etc.
One of the issues is that much of the lost coverage is something people will not know about until they need it.
