Dan Quayle never got over the gaffes he made in the campaign when he ran for and became vice president in 1988.
He became something of a national joke.
Palin doesn't want to let that image of her solidify in this post-election period.
That's why she's doing a round of interviews this week, telling Fox News that "if there is an open door in '12 or four years later, and if it is something that is going to be good for my family, for my state, for my nation, an opportunity for me, then I'll plow through that door."
Later this week she is going down to Miami for the Republican Governors Association annual meeting where she will appear on a panel on the future of the Republican Party called "Looking Toward the Future" and holding a major news conference.
She is determined to make sure her image survives this campaign.
But there are other Republicans looking to take the mantle of the Republican Party.
There's a vacuum of leadership at the top of the Republican Party right now.
There's Louisiana Gov. Bobby Jindal, an Indian-American, who some people call the Republicans' Barack Obama. You also have Gov. Charlie Crist down in Florida.
This is a free-for-all for the leadership of the GOP -- and Sarah Palin wants to be part of it.
She's certainly knocking on the door right now, checking to see if it's locked.
