Palin has scheduled a 3 p.m. ET news conference at her home in Wasilla. The governor’s office offered no further details about the subject of the news conference, but the sources tell CNN that Palin will announce her decision to forgo another run.
"She thinks she has accomplished goals she has set forward," one of the sources, speaking on the condition of anonymity, said. "She sees what a positive influence she has had on people's lives from traveling the country in the last year."
As the 2008 Republican vice presidential nominee, Palin is considered one of the frontrunners for the GOP nomination in 2012. Her decision not to seek another term as governor is sure to stoke speculation that Palin is seriously eyeing a run for the White House.
