For more than a decade, Pennsylvania's two Republican senators, Arlen Specter of Philadelphia and Rick Santorum of Pittsburgh, have avoided open spats. "I don't think we've ever come close to airing our differences publicly," the moderate Specter said of his conservative colleague.
Until now.
As the Senate prepares to debate next month whether to allow federal funding for stem cell research using human embryos, the Pennsylvanians have taken leading roles on opposite sides. Santorum believes such research entails destroying human life. Specter says the stem cells used would come from embryos that would otherwise be discarded.
Their conflicting positions, despite shared constituents and political affiliation, illustrate the rift within the Republican Party over the matter.
