I learn from NPR this am that a penny contains 1.7 cents worth of copper. I'm stoking up the furnace as I write!
On an unrelated topic, I'm waiting to see if Krugman is playing by Obama rules. Several times in past columns he has raked Obama over the proverbial coals for using Republican-sounding talking points in criticizing Clinton's health-care proposals and in calling for a fix for social security. Of course, Obama has never implied that any Republican candidate had a health-care plan that was preferable to Clinton's. Clinton, on the other hand, has said that she and McCain (and presumably Sinbad and Cheryl Crowe) have, while Obama has not, crossed the "commander-in-chief threshold." This is really inexcusable. Don't you think, Paul?
