Sarah Palin: I'll Run For President 'If There's Nobody Else To Do It' (VIDEO)

Sarah Palin explained Thursday the circumstances in which she would run for president in 2012, seemingly saying that she'd only throw her hat in the ring if nobody else was doing it.

Here's what the former Alaska Governor told "Entertainment Tonight":

"It's going to entail a discussion with my family [and] a real close look at the lay of the land, and to consider whether there are those with that common sense, conservative, pro-Constitution passion, whether there are already candidates out there who can do the job, and I'll get to be their biggest supporter and biggest help-mate, if they will have me.

"Or whether there's nobody willing to do it, to make the tough choices and not care what the critics are going to say about you, just going forward according to what I believe the priorities should be.

"If there's nobody else to do it, then of course I would believe that we should do this."

Though similar to her previous inklings regarding her presidential ambitions, Palin's latest answer seems significantly less enthusiastic.

In September she gave Fox News a more confident variation:

"If the American people were to be ready for someone who is willing to shake it up, and willing to get back to time-tested truths, and help lead our country towards a more prosperous and safe future and if they happen to think I was the one, if it were best for my family and for our country, of course I would give it a shot," Palin said. "But I'm not saying that it's me. I know I can certainly make a difference without having a title. I'm having a good time doing exactly that right now."

Less than a week after that, she told Fox News again that it would come down to the strength of other candidates in providing solutions for national security and the economy.
