President Obama and former Alaska governor Sarah Palin will both come to Iowa on Tuesday, coming within three hours of each other and, in the process, taking attention away from the growing field of official GOP presidential candidates stumping through the Hawkeye State.

Continuing his recent focus on the economy, Obama will tout his vision for increasing American manufacturing jobs at a factory in Bettendorf, in the eastern part of the state. Palin will head to Pella, in central Iowa, for the premiere of “The Undefeated,” a film about her political rise.

Obama speaks at 1 p.m. Central time; the Palin movie opens at the Pella Opera House four hours later.

It’s not clear whether Palin will give formal remarks after the movie, which was produced by the conservative Victory Film Group. The film will be formally released in 10 cities (Houston, Indianapolis, Oklahoma City, Orlando and Phoenix, and the suburbs of Atlanta, Dallas, Denver, Kansas City and Los Angeles) on July 15.

“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 released by Victory.

Officially, neither the president nor the former vice-presidential candidate are making campaign appearances. Palin has not yet entered the 2012 Republican field.

Obama has announced his reelection campaign, and the trip to Iowa is not surprising, given that he appears in a swing state nearly every week for an “official” presidential trip.
