From The Morning GrindSen. Rick Santorum (R) has gained significant ground in the last two months on State Treasurer Robert Casey (D), who is challenging him for his Pennsylvania Senate seat, a new Quinnipiac University poll released this morning shows. But Santorum still faces an uphill battle to win re-election, as 49 percent of Pennsylvania likely voters say that the incumbent should not be re-elected.
The poll says that Casey leads Santorum 48 percent to 42 percent among likely voters, with Green Party candidate Carl Romanelli collecting 5 percent and the remaining 5 percent of voters undecided. In a head-to-head match-up, Casey has a 47 percent to 40 percent advantage over Santorum, while a June 21 poll by the university had Casey leading Santorum 52 percent to 34 percent.
Democrats view the Santorum seat as a must win for the party to wrest control of the Senate from Republican hands in November. In an effort to help dilute Casey's support, Republicans helped Romanelli collect signatures to ensure he was on the November ballot.
"Bob Casey's lead over Sen. Santorum has shrunk to single digits in part because the Green Party candidate is siphoning votes from the Democratic challenger," Clay Richards, assistant director of the Quinnipiac University Polling Institute, said in a statement released with this morning's poll. "It's not surprising Sen. Santorum has narrowed the gap, but his bid for re-election is still in trouble as long as almost 50 percent of the voters say he does not deserve another term."
