Bush's "health care" proposal was smoke and mirrors and magic asterisks to throw big tax deductions at favored people. The WaPo piece shows that it would have done very little to actually insure people.
Yes, Obamacare has changes to the tax code. And horror of horrors, it actually pays for itself by collecting some taxes and reducing some overpayments.
The point remains, though, that Bush's proposal wasn't comprehensive and didn't cover as many people as anything that claims to be a quasi-universal health insurance scheme would do.
HTH.
Cheers,
Scott.
