"Two years ago, my engagement was on the state of Alaska -- largest, most diverse state in the union, 20 percent of the U.S. domestic supply of energy coming from our state, while desiring to and working towards ramping up that domestic energy production. That was my focus. Now, of course, my focus is -- has been enlarged. So I sure as heck better be more astute on these current events, national issues, than I was two years ago," she said.
Palin said first and foremost, her focus was on her children.
"I want to be a good mom. And I want to raise happy, healthy, independent children. And I want them to be good citizens of this great country."
But she added, "I do want to be a voice for some commonsense solutions. I'm never going to pretend like I know more than the next person. I'm not going to pretend to be an elitist. In fact, I'm going to fight the elitists because for too often and for too long now, I think the elitists have tried to make people like me and people in the heartland of America feel like we just don't get it, and big government's just going to have to take care of us."
But in the meantime, Palin is campaigning for Republican candidates around the country, such as for Gov. Rick Perry in Texas and Senate-candidate Rand Paul in Kentucky.
"I have want to speak up for the American people and say, "No, we really do have some good commonsense solutions." I can be a messenger for that. Don't have to have a title to do it."
