I am comparing the wllingness to believe something just because it is damaging to the opposition - even when it has not been proven to be true.
I am not believing nor disbelieving. I am agnostic.
In the case of the Palin situation it was clearly a made up story.
What is the reason behind this? Who did it? Why? Who benefits? Last I checked they are standing behind the story and claimed they had a tape of the call.
