At first glance, there appears to be much to admire in Gov. Sarah Palin of Alaska, Sen. John McCain’s choice as his vice presidential running mate. Just 44 years old, she is a talented and upbeat person who excelled in basketball and beauty pageants, music and moose hunting. Since entering politics she has shown independence and a clear moral compass. On Alaska’s oil and gas commission, she blew the whistle on a fellow Republican’s conflict of interest. Her 2006 campaign for the state’s highest office began as an insurrection against her party’s old guard. In choosing her, McCain said that Palin’s experience equips her to help “shake up Washington.”
