Sure, there was a recession, which I alluded to, and other stuff, well, I was working with a few sentences, not a book.

The CBO graded obamacare as reducing medicare costs (the biggest driver of our budget deficits). Expanding coverage should have a positive impact on costs, too. But I agree that expanding coverage was at least as important the bill's authors.

I wasn't trying to oversimplify the situation more than is necessary for a few sentence summary -- and people could disagree with my characterization. The coverage towards each president from the Economist is enlightening though, especially when you divorce it from policy or compare their coverage of similar policies from both administrations. That's where the hackiness comes in.
