VIGGO MORTENSEN didn't want to miss out on Election Day while filming his latest flick, "The History of Violence,'' in Canada so he staged a polling station on the set. People maggie reports that the "Lord of the Rings" hottie rigged up a mock voting booth and producer Chris Burns used his dog, Rosie, to monitor the voters. Not surprisingly, cast and crew voted for John Kerry though the write-in candidate, Rosie the canine, made a strong showing in second place. Have these people never heard of absentee ballots?
