I agree. She’s *not* stupid despite what the left says, but I do fear she is unelectable. This is key - if her negatives don’t improve beyond what you say, I agree - she’ll do what’s best for her country, and decide not to run, but endorse someone (Cain or *maybe* Bachmann) who she feels has a shot and represents her values.
It's ridiculous for people to try to make this a conservative/RINO thing. There are plenty of conservatives who do not have her extraordinarily high negatives among indies and women, most notably Marco Rubio or Rand Paul. But the O'Donnell/Angle races did not help Palin, because I think it reinforced in the minds of many people that Palin is of that same cut of cloth.
The question people around here need to start asking is not whether she can run an "unorthodox" or "different" campaign, but exactly how such a campaign will persuade people who saw the 60 minutes interview or Katie Couric interview that she is indeed capable. Even John Ziegler's pro-Palin movie had a hard time making her look good in those interviews. That is what she will have to overcome.
