From Brendan Nyhan posting at Pollster:
Once perceptions are formed, they are difficult to break. And we all know how Quayle 2000 turned out. He didn't make it to Iowa. Will Palin?
Incidentally, Jonathan Bernstein over at A Plain Blog About Politics has an interesting take on how Palin fits into the 2012 field; like an issue candidate (a la Kucinich or Paul) but with a much bigger following. I aptly, in my opinion, draws a parallel between her and Jesse Jackson's run in 1984. It's an good read; check it out.
