One, if you liked or loved Palin before, you're going to love this interview and her.
Two, she's going to run in 2012. She wouldn't rule it when directly asked. If getting out of the spotlight was the reason for resigning, she might have bit on that. She was committed to her explanation of why she resigned. Most telling to me was her constant refrain of energy independence, national security and smaller government. That is a campaign mantra and she was on message with it throughout the interview.
This wasn't a chat that was reflective or exploring reasons for her actions, this was a campaign appearance.
I maybe wrong and you can beat me to hell with this in a year or so but it's how it read to me.
