Quinnipiac offers a shocker in the Keystone State:

Pennsylvania Sen. Arlen Specter’s 2010 reelection lead over Republican challenger Pat Toomey has shrunk to a tie with 45 percent for Specter and 44 percent for Toomey, according to a Quinnipiac University poll released today. And voters say 49 – 40 percent that Sen. Specter does not deserve reelection.
Specter, first elected to the Senate as a Republican in 1980 but who switched to the Democratic Party earlier this year, holds a commanding 55 – 23 percent lead over U.S. Rep. Joe Sestak in the race for the Democratic nomination. On the Republican side Toomey buries Peg Luksik 47 – 6 percent.
On May 4, Specter led Toomey 53 – 33 percent in a trial heat; his favorable unfavorable ratio among Pennsylvania voters was 52 – 34 percent and voters said 49 – 41 percent he deserved reelection. In a May 28 Quinnipiac University poll, Specter led Toomey 46 – 37 percent.
“Sen. Arlen Specter’s 20-point lead over former Congressman Pat Toomey less than three months ago has virtually vanished,” said Peter A. Brown, assistant director of the Quinnipiac University Polling Institute.
“Voters see Sen. Specter much less favorably than they once did and are net negative about giving him a sixth term in the U.S. Senate. Independent voters have shifted narrowly to Toomey 46 – 42 percent and say 53 – 35 percent that Specter does not deserve reelection.”

Toomsday is coming.

UPDATE: Toomey’s campaign likes this headline. It’s more fun when you say it aloud in the Schwarzenegger accent.
