Krugman: Mary's Quite Contrary

You may have read about, or perhaps even viewed, Mary Matalin hitting Paul Krugman as a mere "polemicist" on a Sunday yack show yesterday.  Now Paul has replied online, pointing out that what caused her ire (poor Carville) was Krugman challenging one of her "facts."   Her $1.7 trillion in purported savings from GOP-demanded caps on deductions has two major problems and to fix them (which clearly be needed)  the actual savings would be down to $450 billion, the White House says.
