The hell she didn’t and you know it. You don’t want to admit the truth.
You should read C4P if you stomach the ostriches there. Most of September the posters on that site were clamoring that she'd announce, one way or the other, in September. Why? Because they believed Palin clearly said she would announce by the end of that month. It is what everyone heard her say. They were sure for awhile it would be Sept 3, then it was Constitution Day (divined from the painting on the side of her bus). Now they are twisting her words and looking for outs and caveats. "Oh, she just said she'd decide, not announce" they claim now.
This is coming from someone that supported her through near the end of spring and also expected her to be a serious candidate and conservative champion. I was willing to overlook some of the bad signs for quite awhile - including early on making excuses for her quitting her job as Governor. Finally it occurred to me that Palin simply wasn't serious. Any constructive criticism of her among her followers was met with hysterical, illogical rage. They really believe the woman can do no wrong and that even her dumbest mistakes are part of some grand plan. It's downright disturbing because it proves to me that people of ALL ideologies are capable of falling into the cult of personality trap. I thought conservatives were a little less likely to lose their minds this way, but Palin supporters demonstrate otherwise.
