The headline on the new poll out this morning from Quinnipiac University reads, "Santorum Still Slipping In Pennsylvania Senate Race." Quinnipiac has Santorum trailing Casey by 13 points (49-36) now, which is a slight deterioration from the eleven point deficit he was running in their last poll taken in April (48-37).

The Quinnipiac numbers contrast with the Franklin & Marshall Keystone poll released last week which seemed to indicate the race was trending in the other direction.
