Well, I feel a bit better about the Derb family’s charitable donations now. I happened to have all my tax documents on the desk in front of me while reading David’s post. Our 2007 charitable donations were 0.4 percent of our un-adjusted gross family income, just that same as the Obamas in 2002. It would of course be churlish of me to further note that the Obamas, even in 2002, had two big fat Ivy League incomes, while the Derbs are poor as church mice. I therefore shall not do it.
