(CNN) - Sarah Palin told CNN on Monday that she plans to take her "One Nation" bus tour to Iowa, the state that votes first in the race for the Republican presidential nomination.
"I'm sure at some point I will be going to Iowa," Palin said during a visit to Fort McHenry in Baltimore. "At some point."
The comments come on the heels of a RealClearPolitics story that said Palin is planning a visit to Iowa in June, the same month a documentary about her rise to power is set to debut in the Hawkeye State.
The trip would be Palin's first visit to Iowa since December, when she stopped there during a book tour. She also addressed a fund-raising dinner for the Iowa Republican Party last September.
Palin and her family were mobbed by television cameras after her arrival at Fort McHenry, the fort that famously defended Baltimore from a British assault during the War of 1812. The battle served as the inspiration for the national anthem, Francis Scott Key's "Star Spangled Banner."
Asked about her 2012 thinking, Palin said her family's concerns come first. But she also said the unsettled nature of the Republican presidential field has left the door open for other candidates, herself included, to join the nomination fight.
"It's going to be a changed-up field between now and when deadlines finally arrive for declaring," Palin told CNN.
While she said she is "satisfied" with the Republicans who are already in the process of campaigning, she predicted that the field "is going to change up a lot."
"I believe that there are many more out there who have much more to add," she said. "Competition breeds success. I hope there is going to be vigorous debate and a lot of good aggressive competition even in the primary so our voters have a good choice."
Unprompted, Palin brought up Texas Gov. Rick Perry, who said last week that he plans to consider a presidential bid.
"I think he would be a fine candidate," she said. "We have a lot in common. I really like him. But there are so many candidates and potential candidates out there who have so much to offer."
