Reportedly, a list of polling places in Pennsylvania will not be publicized because state officials are concerned that terrorists could disrupt elections. This decision was influenced by the terrorist bombings that occurred days before Spain's national elections in 2004. However, information on individual polling places will remain available on the state voter services web site. Many nonprofit organizations that conduct get-out-the-vote efforts will certainly face difficulties because of this.

Furthermore, the attacks in Spain before that country's national elections in 2004 did not target polling places, and the U.S. had a national election in 2004 as well which was plagued by a shortage of machines, disproportionate disenfranchisement of the poor and minorities, and machine irregularities, but there certainly were not any terrorist attacks that year on U.S. soil. And if someone did want to attack a polling location, they could still simply call the state or county elections bureaus.
