Follow this link to an article by two economic advisers to Barack Obama.They claim that McCain’s plan is similar to what was in the bailout bill that was already passed and signed into law, except for one major difference.  This difference is what makes McCain’s plan a bad idea.

But today we learned of a detail that makes his plan significantly different — and much worse.

They don’t specify in the article where they learned about the detail, so there is no way of knowing if their report is accurate.
