Monday, September 15th 2008, 9:52 AM Beck/Getty Gov. Sarah Palin The current lie of the presidential campaign, current but certainly not last, is that you are some kind of lousy, sexist bum if you question Sarah Palin's lightweight credentials to be vice president of the United States, or the judgment of the 72-year-old who put her on the ticket in the first place. It means you're supposed to do about as much vetting on her as John McCain. She's a spunky mom, she has a son who's a soldier, she loves guns and hates Roe vs. Wade, and don't worry...
