LEWISBURG, Pa. – Maurice Brubaker probably wouldn’t have gone to see “Fahrenheit 9/11″ on his own, but free admission helped change the Republican’s mind. Brubaker, chairman of the Bush/Cheney campaign team in Union County, was among at least 40 people who went to the Campus Theatre on Saturday to take advantage of a free showing for card-carrying GOP members. I don’t think you can consider it a documentary, because I don’t think both sides were represented,” Brubaker said of the Michael Moore film that criticizes the Bush administration’s response to the Sept. 11 attacks.
