You know...I think Palin is reacting with a huge amount of maternal instinct. Then the finacial burden of lawyers to clean up all the investigations is getting to her. I think she ended up not being able to focus her job anymore and knew it was time to move on. I have to laugh because the political analyst were saying it was a brilliant political move for the Presidential election in 2012 and all I could read out of it is that she's sick of being a tabloid figure.
