Governor Sarah Palin announced Friday that she will step down as Alaska's chief executive by the end of the month, and will not see re-election in 2010.
Palin, a Republican, was elected governor in 2006. She was tapped as Arizona Sen. John McCain's vice presidential running mate last year.
Lt. Gov. Sean Parnell will be sworn in on July 26. He'll join us this morning in the CNN Newsroom, beginning 6am ET/3am PT.
A Republican source close to Palin's political team told CNN's John King the governor's "book deal and other issues" were "causing a lot of friction up" in her home state, and that he believes that she is "mapping out a path to (the GOP presidential nomination in) 2012."
Veteran GOP strategist Ed Rollins, however, questioned that assumption. "You don't just quit with a year and a half to go. You certainly don't do this as a stepping stone to run for president."
What do you think about Governor Palin's decision to step down with a year and half left in her term?
