Save the Environment: Repeal the Mortgage Interest Deduction

That's the title of a great Tax Policy Blog post:

Powerful U.S. Rep. John Dingell revealed Tuesday new details of his plan to cut global warming, including adding a 50-cents-a-gallon tax on gasoline and ending the mortgage tax deduction on what he called "McMansions," homes larger than 3,000 square feet.

On the same blog, France rejected a mortgage interest deduction.
