I see her resignation as a positive thing from a few different tangents. She can now truly take off the gloves if she decides it is what she wants to do. She can stop the pointless waste of taxpayer money fighting an endless stream of frivolous ethics complaints (gee, a politician who isn't immediately ready to piss away millions of taxpayers dollars to further her personal ambitions, imagine that). She is free now to recuperate the $500k+ of debt incurred from those frivolous lawsuits without that being used against her as well (seeing as how the left uses tactics to bankrupt their adversaries).
Being a politician is not the same as enlisting in the military as far as the ‘she should have served out her term’ argument goes. The reasons she personally spelled out make me WANT to vote for her AND POLITICIANS WHO BEHAVE IN THE SAME MANNER! She best served her constituents with this move after deciding not to run for reelection regardless of her future choices of whether to run for another political office.
We NEED more politicians who think of their constituents, and I think it's more than obvious that our current batch of representatives could care less about those they are supposed to ‘serve’.
I expect a politician that I vote for to fulfill his/her official duties...not use my state as a stepping stone to higher office. I didn’t approve of this when the Dems did it (Obama, Clinton). I can not approve the GOP engaging in this behavior either. Her behavior makes me less likely to vote for her. I would have to understand her actions completely before having enough confidence to help elect her to the highest office in the land.
