It is easy for Romney with his bottomless pit of money to criticize Palin. But....In my opinion, given the numerous friviolous lawsuits against Palin she did the only sensible thing possible.
Ok...Now I will read the article.
The smartest thing they could have done was to leave Palin alone and try to survive in the post-election political environment. She would have had a tough time winning reelection because the Democrats were now against her and so were many in her own party. Of course she might have done well, showed her meddle, and been left in a strong position for 2012. That was what they feared, so the national Dims went full bore against her. The timing of her resignation came before she suffered any significant political defeats. This left her free to flank their efforts to marginalize her and to appeal to her many supporters in the lower 48. What frustrates them is that she is such an unconventional politician.
