Sarah Palin | PERSON

In this Oct. 15, 2009 photo, Roger Marks shows a presentation he prepared on former Gov. Sarah Palin's Alaska Gasline Inducement Act at his home in Anchorage, Alaska. Palin hit the vice presidential campaign trail last year and touted what Alaska could provide for the rest of America, a natural gas pipeline to help lead the country to energy independence. When a pipeline might be built remains a giant question for Alaskans who need the project to support a vulnerable economy and for the Lower 48 states that need the gas, and a petroleum economist who spent more than 25 years in the Alaska Department of Revenue says it may never happen under Palin's plan.

In this book cover image released by Harper, "Going Rogue: An American Life," by Sarah Palin, is shown.
