John Fund of the WSJ said specifically that Moveon.org got hold of the supposedly secret info on which precincts were to be exit-polled.
Moveon then sent floods of fake voters into those precincts; when they emerged, they 'volunteered' to be exit-polled and gave the pollsters their left-wing data.
Fund said this on the John Batchelor radio program tonight.
Sabotage via leaked information makes complete sense. I read on another thread here that Ann Coulter is saying basically the same thing, with confirmation of exit poll locations being leaked via postings on DUmmy prior to Election Day.
I was actually exit polled myself here in Nevada; The woman doing the polling was simply sitting at a chair outside my polling place. I walked up to her and volunteered to take her survey. Very easy for criminally inclined members of an organization like MoveOn.org to sabotage the polls if they knew ahead of time where the polling places were set-up. All that is needed is a demographically varied group of members to walk into and out of such polling places and then "volunteer" to take the exit poll...
