So here's my question: with all the real fodder on S. Pallin - Pregnancies! DUIs! Dead moose! Her energy policy! Her lack of international experience! (listed in order of importance, obviously) - why bother with badly Photoshopped pictures?
This is an old tactic and it is called "poisoning the well." I will theorize that the bikini shot is put out by the Palin people, in order to use it to cast doubt on all the genuine damaging photos out there.
