Gosh Mr. Santorum

Pennsylvania GOP officials claimed there were reports that some machines were changing Republican votes to Democratic votes. They asked the state to investigate and said they were not ruling out a legal challenge.

According to Santorum's camp, people are voting for Santorum, but the vote either registered as invalid or a vote for Casey.

Asked if the party would consider legal action, state Republican executive director Scott Migli said, "We've got all options on the table at this point. We feel like the electoral system has been left up to computer technicians."
