A new Quinnipiac University poll finds Democrat Joe Sestak surging into a statistical tie with Republican Pat Toomey in a hypothetical general election match up in the Pennsylvania Senate race. Sestak gained six points in the last month while Toomey's support remained solid, resulting a two point Toomey lead:

Toomey (R) 42 (nc vs last poll in April)
Sestak (D) 40 (+6)
Undecided 16 (-6)

All three public polls taken in the last week now show Sestak within 1-2 points of Toomey.

Meanwhile, Toomey ticked up slightly in a potential match up against Arlen Specter:

Toomey (R) 47 +1)
Specter (D) 40 (-1)
Undecided 12 (nc)

Toomey's average lead over Specter now stands at seven points as well.

Specter's attack on Sestak in the primary appears to have taken a heavy toll on his image. Last month, 71% of Democrats and 35% of Independents held a favorable view of Specter. This month, those numbers have dropped to 56% and 30%, respectively. Overall, 50% of Pennsylvanians now hold an unfavorable view of Specter - an all time high in the Quinnipiac poll.

Conversely, Sestak's favorable ratings have jumped across the board: up 7 points among Democrats to 40%, up 10 points among Republicans to 23%, and up 15 points among Independents to 31%.

In the governor's race, Democrat Dan Onorato is now within shouting distance of front runner Tom Corbett, gaining a net six points in the last month. Corbett remains comfortably ahead of other potential Democratic gubernatorial nominees:

Corbett (R) 43 (-2)
Onorato (D) 37 (+4)
Undecided 19 (-2)

Corbett (R) 47 (-1)
Wagner (D) 28 (-1)
Undecided 23 (+2)

Corbett (R) 49 (-1)
Hoeffel (D) 26 (-2)
Undecided 22 (+1)
