Actually, I heard Obama came up with that plan first, and then McCain blathered on about how it was his plan (and only his plan) in the debate. It's so stupid that those two fight each other over pathetic, unworkable, idiotic ideas.
Tracking down, verifying, appraising and negotiating millions of mortgages will be a nightmare. It will also be a door to a lot of corruption. It will require a whole new department within the Treasury.
People already know if McCain can't even run his campaign correctly, how can he run the country?
