Sarah Palin’s bus appears to be parked for now

Is Sarah Palin already finished with her national bus tour?

While the Alaska governor hadn't publicly announced additional stops beyond her East Coast jaunt earlier this month, Palin aides had hinted she'd take her bus tour to key primary states such as Iowa and South Carolina.

But according to Real Clear Politics' Scott Conroy, those plans are now in "limbo," as Palin has opted to stay in Alaska, where "skies are currently alight for over 19 hours a day and the Bristol Bay salmon fishing season is nearing its peak."

A spokesman for Palin did not respond to a request for comment. But the report has set off a fresh new round of speculation about what exactly Palin is up to. Is she thinking about making a bid for the GOP nomination? Or is this a sign that she's no longer entertaining a 2012 run?

Palin hasn't exactly been in hiding. She's appeared a few times on Fox News in recent weeks and has kept up a regular stream of messages on Twitter.

Last week, Palin laughed off a report by the American Spectator that she was planning to kick off a presidential campaign as soon as this week.

"Really," she tweeted. "Guess they forgot to inform me 'what I'm expected to do' next week."

All of this comes as a new documentary about Palin is set to premiere in Iowa in coming weeks and expand into nationwide release on July 15. It's unclear if the ex-governor plans to attend any of the screenings, though as Conroy reports, her political action committee, Sarah PAC, is already raising cash off the film.
