Candidates from both parties seeking spots on the Pennsylvania primary ballot have until today to submit petition signatures to the Department of State. Dave McCormick, who is challenging Senator Bob Casey in the fall, made Lititz the first stop on a state bus tour Saturday. He was joined by state Treasurer Stacy Garrity and Auditor General Tim De-Foor, who are both seeking their second, four-year terms. Dave Sunday, the York County district attorney who’s running for attorney general, was also at the rally and signature-gathering event.
