The only secret stoner film masquerading as a holiday classic, Elf, was the first choice on the west coast and basically everywhere marijuana is decriminalized. But it was also big in the Dakotas, Maryland, Delaware, and Alaksa -- which is kind of like the North Pole, only with more grizzly bears and shotguns.
The Griswolds of National Lampoon's Christmas Vacation were a favorite in Nebraska, Kansas, Oklahoma, Tennessee, and Pennsylvania. A Christmas Story, with its 1950's storyline and cautionary tales about licking frost, won out in Ohio, West Virginia, and Minnesota. Hugh Grant fans will probably despair over Love Actually only winning among the cosmopolitan snobs of Washington, DC, but the rest of America agrees.
Far and away the biggest winner was The Polar Express, which won in 26 states.
