WASHINGTON (CNN) - Arlen Specter's Republican polling firm, Public Opinion Strategies, is resigning from the Pennsylvania senator's campaign following his party switch.
"Senator Specter has been a record-setting U.S. Senator, and we have been part of his campaign team in 1992, 1998, and 2004, but because of his surprising decision to switch parties today, we will no longer be involved," said Specter pollster Glen Bolger in a release Tuesday. "As Republicans, we are disappointed by Senator Specter's decision."
Public Opinion Strategies does polling for 15 GOP senators and has worked for Joe Lieberman, who left the Democratic Party to become an independent in 2006.
