There are phone workers who call with any number of story lines..."taking a poll" "Registration drive"...and ask if you will be voting...you say NO, they put you on a list and vote for you. If you say you are GOP and will vote, there is another list for you and they will still send someone to vote for you. IF it is caught and you contest it your vote is either negated or made "provisional", in which case it may or may not be counted   2000  at all depending on how close a race is. Many liberals don't consider this fraud...ends justify the means. I suspect at least 1 in 3 dem votes in critical areas are fraudulent. It's not hard to find precincts where more dems cast votes than the total of the entire population.
