Sarah Palin is traveling to Iowa on Tuesday, in a move that will again once again spur talk of her presidential ambitions.

The former Alaska governor will appear at the premiere of “The Undefeated,” a documentary about her political career, on Tuesday at the Pella Opera House in Pella, organizers announced early Saturday.

“We are very excited to visit historic Pella and its opera house and look forward to seeing the finished film for the first time with fellow Americans from the heartland,” Palin said in a statement.

The move is the latest example of Palin, who hasn’t had the active schedule of a presidential candidate, dipping her toe in the water. It also comes the day after Rep. Michele Bachmann (R-Minn.) announced her candidacy in Iowa, where she is one of the frontrunners, according to a Des Moines Register poll. If Palin entered the 2012 race, she and Bachmann would be vying for the same tea-party base.

Palin was in New Hampshire June 2, the same day former Massachusetts governor Mitt Romney announced his campaign.

When talk of a Palin-for-president campaign died down this spring, Palin announced that she would be going on a bus tour. And a media frenzy ensued.

This week, she fended off reports that her bus tour had been canceled or is on hiatus — which many saw as evidence that she’s not serious about running for president.

This is a busy week in Iowa, with President Obama on Tuesday visiting an Alcoa factory in Bettendorf.
