Asked about possible candidates to serve as his Treasury secretary, John McCain said in Tuesday's presidential-candidate debate that Meg Whitman was a top candidate. His running mate, Sarah Palin, loves to talk about putting the state jet on eBay (even though, as is all too typical for eBay sellers these days, it didn't actually result in a sale). Whitman's record at eBay is mixed; she probably stayed three years too long. But since we're on the topic, why not put all the worthless mortgage securities the government is buying on eBay? The listing fees alone will be a major boon to the Silicon Valley economy.
