Club For Growth: Specter's Stimulus Support "The Ultimate Act of Treason"

Soloveichik said that no specific potential primary challengers have stepped forward just yet. Toomey, who now serves as the Club's president, is currently eyeing a possible campaign for governor of Pennsylvania, not Senate. But she sounded optimistic: "Whenever there is a constituency for a challenger, then people start looking at the opportunities."

Meanwhile, a Democrat has now thrown his hat in the ring for this race: Joe Torsella, a former deputy mayor of Philadelphia and the founder of the National Constitution Center. Other Dems are looking at the race, too. If a Republican candidate is able to successfully mobilize right-wing ire against Specter in the primary, then that Democratic nomination could become a very valuable thing, indeed.
