If by ‘recently’ you mean 7 to 8 years ago, yes. Specter had also gone to the mat and had put all of his own clout on the line to help Santorum in his previous close races which no doubt helped put him across the finish line, including in 2000 where the head winds were against him with Gore carrying the state. When Specter found himself in a tight spot Santorum returned the favor. It would have required a lack of personal and professional integrity for Santorum not to have done so. Integrity is a disqualifier for some based on the nonsensical vitriol spewed toward Santorum over this issue, but not to me - nor to Pat Toomey.
Thanks for the well reasoned response. I’m sure it helped a few people out.
