Republican strategists took as a bad omen Santorum's primary result in 2006, in which he ran unopposed for the Republican nomination. Republican gubernatorial nominee Lynn Swann, also unopposed in the primary, garnered 22,000 more votes statewide than Santorum in the primary, meaning thousands of Republican voters abstained from endorsing Santorum for another Senate term. This may have been partly due to Santorum's support for Arlen Specter, over Congressman Pat Toomey in the 2004 Republican primary for the U.S. Senate. Even though Santorum was perceived to be only slightly less conservative than Toomey, he joined virtually all of the state and national Republican establishment in supporting the moderate Specter. This led many socially and fiscally conservative Republicans to consider Santorum's support of Specter to be a betrayal of their cause. However, Santorum said that he supported Specter to avoid risking a Toomey loss in the general election, which would have prevented President George W. Bush's judicial nominees from getting through the Senate. Santorum said Supreme Court Justice Samuel Alito would not have been confirmed without the help of Specter, who was chairman of the Senate Judiciary Committee at the time.
