This woman quoted in the Philadelphia Inquirer is saying the exact same kind of thing I heard repeatedly from folks who showed up for Santorum rallies on Saturday:

“The Democrats aren’t as awake as the Republicans to how serious and far-reaching are the dangers we face in this world,” said Hay, 48, of Newtown Township. “I know this sounds overdramatic,” she said, “but I believe the president very literally has his finger in the dike protecting Western civilization, and he deserves our support.”

To put it badly: Don’t forget that for Pennsylvanians, terrorism and 9/11 in particular hit close to home.
