McCain vs Obama: Tax Reform

In today's NY Times, David Leonhardt keeps the dream of tax reform alive, with a focus on the tax treatment of housing. An excerpt:

Barack Obama has called for a new mortgage tax credit to make the tax code fairer. Politics being what they are, he hasn’t proposed a cut in the current [mortgage interest] deduction, but his idea still represents progress. John McCain has arguably gone further, saying that as president he would want to send Congress a tax plan along the lines of the Bush panel’s — and then demand an up or down vote with no amendments.
