...but you left out the part where it was also the best political decision she could have made also.
Now she is making money, campaigning for the 2010 midterms, and very visible...playing it her way.
To be true to my own beliefs, that is the worst of the motivating reasons. I don't want a pol who motivates for politics. I want a pol who motivates for the public good. I believe she acted in the public good, in resigning.

As all my posts here indicate, I do not think that her resignation was a good political move at all...handing your opponents the tools to label you a quitter is just dumb if you want a future politicical career.
