“It’s going to be a changed-up field between now and when deadlines finally arrive for declaring,” Palin told CNN.

While she declared herself “satisfied” with the Republicans who are already in the process of campaigning, she said 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.”
