It all went down at Chicago's Admiral Theatre -- where a 21-year-old Palin doppelganger named "Bia" (above) won $2,500 after proving she has nothing to hide on some very hot button issues.
According to the organizers, a portion of the the proceeds went to a "legitimate tea party organization," and while Sarah was invited to judge ... we're told she never got back to them on the offer.
Wonder why?
