Sen. Arlen Specter has a tough primary coming up next week against Rep. Joe Sestak, and the Service Employees International Union, which has endorsed him, is sending this mailer to members to help the incumbent (.pdf here SEIU Specter mailer.pdf, image below). SEIU says it represents nearly 100,000 members in the state.
"Senator Specter has been there for us and now we are proud to stand with him in making sure he can keep working on behalf of Pennsylvania families," said Eileen Connelly, Executive Director for the SEIU PA State Council.
