The Invisible Primary, 10/28

Tracking the GOP race to 2012

Sarah Palin got an advance of $1.25 million for her memoir; Levi Johnston, meanwhile, says he plans to "leak some things" on Palin; the former Alaska governor also encouraged her supporters, via Facebook, to rally around the Republican Governors Association and the GOP's gubernatorial candidates in New Jersey and Virginia; Rick Santorum addressed a FreedomWorks event in North Carolina and said Americans are living in "fear" in the Obama era; and Newt Gingrich criticized GOP support for Conservative Party candidate Doug Hoffman in New York's 23rd district as a "purge."
