A top staffer to Eric Cantor is leaving the House majority leader's office to launch a Super PAC aimed at raising Cantor's national profile, sources told Influence Alley.The PAC will be run by Cantor's deputy chief of staff John Murray and would give Cantor a vehicle he could use to run for vice president, should the opportunity arise, said a source close to the majority leader's office, who asked not to be named because the source was not authorized to speak publicly. Murray's departure from Cantor's office is imminent, the source said.
