How do you know that all of the 'bloggists' who initiated these ethics complaints are 'left wing'? Do you have personal knowledge of the political affiliations and leanings of each and every one of them? Or are you merely parroting the accusations of the right wing bloggists who generally support Palin and populate the web sites that you rely upon for your information?

Perhaps you should also consider that at least some of these ethics complaints could have been dismissed due to a lack of supporting evidence, and not because they were frivolous to begin with. Many times, ethics violations turn on intent, which is not always easy to prove. And it is a basic concept of ethics that it is not enough to avoid actual conflicts of interest; one should avoid the appearance of a conflict of interest as well (a principle that seems to have been lost or ignored  by a great many public officials). It could very well be that Ms. Palin engaged in activities that gave the appearance of a conflict of interest, but evidence proving that a conflict did in fact occur was lacking. Obviously, I am speculating here, because I do not know the specifics of each of these dismissed complaints. But then, I suspect that neither do you.
