Suppose she said she decided not to run because she can do a better job 'saving the country' by not running? would you buy that?
That's not a complete enough scenario for me to make a call on. Just how would she do a better job of saving the country by not running, and how would she explain that to her supporters?
Before you dream up an answer, I can tell you that few of her supporters would buy it. There is no power in this country like the presidency to make real and lasting change, and we all know that.
